| CVE-2026-102406 | 1 Elastic | 1 Kibana | 2026-10-06 | 8.8 High |
| Authorization Bypass Through User-Controlled Key (CWE-639) in Kibana could lead to cross-tenant data interception. In this context, "tenant" refers to a user or team sharing the same Kibana deployment, not a separate Elastic Cloud organization or customer. Kibana's Fleet package installation process allowed a user holding delegated Fleet package-management privileges, without direct Elasticsearch administrative privileges, to claim a data stream identifier already in use by another tenant. Because ownership of that identifier was not verified before Fleet applied the uploaded package's generated index and ingest-pipeline settings to already-existing infrastructure, an attacker could redirect an existing tenant's data stream through infrastructure under their control. This exposed the affected tenant's subsequently ingested data to unauthorized disclosure and modification, and prevented that data from reaching its intended destination. Interception could continue even after the malicious package was removed, requiring separate remediation of the affected infrastructure. | ||||
| CVE-2026-102407 | 1 Elastic | 1 Elasticsearch | 2026-10-06 | 5.4 Medium |
| Incorrect Authorization (CWE-863) in Elasticsearch can lead to unauthorized data stream modification via Accessing Functionality Not Properly Constrained by ACLs (CAPEC-1). An authenticated user with sufficient privileges over a single resource could use the Modify Data Streams API to modify a data stream to which they were not otherwise authorized, potentially injecting data into it or affecting its ability to be searched normally. This issue does not allow an attacker to read the contents of a data stream they do not otherwise have access to. | ||||
| CVE-2026-102408 | 1 Elastic | 1 Elasticsearch | 2026-10-06 | 4.3 Medium |
| Inefficient Regular Expression Complexity (CWE-1333) in Elasticsearch can lead to denial of service via Regular Expression Exponential Blowup (CAPEC-492). The ES|QL CHUNK function's recursive chunking strategy accepts a list of user-supplied regular expressions used as text-splitting separators, without validating their computational complexity or bounding their execution time. An authenticated user with read access to any text-based index can submit a specially crafted regular expression that triggers catastrophic backtracking, consuming excessive CPU on Elasticsearch worker threads and degrading query throughput for other tenants on the affected node. The cluster does not crash as a result of this issue. | ||||
| CVE-2026-102409 | 1 Elastic | 1 Elasticsearch | 2026-10-06 | 6.5 Medium |
| Uncontrolled Recursion (CWE-674) in Elasticsearch can allow an authenticated user with low privileges to terminate an Elasticsearch node, resulting in denial of service, via Excessive Allocation (CAPEC-130). | ||||
| CVE-2026-102411 | 1 Elastic | 1 Elasticsearch | 2026-10-06 | 6.5 Medium |
| Allocation of Resources Without Limits or Throttling (CWE-770) in Elasticsearch can lead to Denial of Service via Excessive Allocation (CAPEC-130). Elasticsearch enforces a size limit on the user-supplied metadata field for each individual template resource, but does not limit the total memory used when multiple such resources are retrieved together. A user holding the *manage_index_templates* cluster privilege can register multiple resources each within the individual limit. Retrieving them together materializes all of their metadata values in memory at once, exhausting available heap and causing the affected node to fail with an out-of-memory error, resulting in a denial of service. | ||||
| CVE-2026-102412 | 1 Elastic | 1 Kibana | 2026-10-06 | 6.5 Medium |
| Incorrect Authorization (CWE-863) in Kibana can lead to sensitive information disclosure via Accessing Functionality Not Properly Constrained by ACLs (CAPEC-1). An authenticated Kibana user with limited Fleet management privileges could access sensitive credential material that should be restricted to users with Fleet settings administrative access. Successful exploitation could allow an attacker to obtain private cryptographic key material configured for Fleet Server host connections, potentially enabling impersonation of trusted Fleet infrastructure components in deployments where those keys are actively used. | ||||
| CVE-2026-103009 | 1 Elastic | 1 Elasticsearch | 2026-10-06 | 7.1 High |
| Authorization Bypass Through User-Controlled Key (CWE-639) in Elasticsearch can lead to Information Disclosure via a specially crafted cross-cluster search request that references an unauthorized shard identifier. Elasticsearch contains an authorization bypass weakness in its handling of cross-cluster search requests made through the Remote Cluster Security (RCS) 2.0 model. An authorization check validates a request against one identifying attribute of the target shard, while a separate, independently-supplied identifying attribute in the same request determines which shard is actually accessed. A holder of a cross-cluster API key authorized for one index can craft a request whose two identifying attributes refer to different indices, causing the request to be authorized against an index they can access while actually operating against a different, unauthorized index. This can expose that index's document contents, field mappings, and other metadata, and in limited cases allows modification of retention-lease state on the unauthorized index. | ||||
| CVE-2026-96577 | 2 Oc-mirror, Redhat | 3 Oc-mirror, Assisted Installer, Openshift | 2026-10-06 | 7.1 High |
| A flaw was found in oc-mirror. During mirroring operations, the embedded local cache registry binds to all network interfaces without authentication or encryption instead of restricting access to the local system. An unauthenticated attacker on an adjacent network can connect to the exposed service to push tampered container images, delete cached images, or access mirrored content. | ||||
| CVE-2026-83589 | 2 Oauth2 Proxy Project, Redhat | 2 Oauth2 Proxy, Openshift | 2026-10-06 | 6.1 Medium |
| A flaw was found in oauth-proxy. The application fails to properly validate the destination redirect parameter (`rd`) during post-login redirection. A remote attacker can exploit this vulnerability by enticing a user to follow a specially crafted link, resulting in the user being redirected to an arbitrary external website after authenticating. This open redirect can be leveraged to conduct phishing attacks or credential theft. | ||||
| CVE-2026-49329 | 1 Redhat | 2 Openshift, Openshift Container Platform | 2026-10-06 | 7.5 High |
| A flaw was found in openshift/oauth-server. The OAuth login and error page endpoints pass the unauthenticated Accept-Language header to golang.org/x/text/language.ParseAcceptLanguage() without input validation. A bypass of the CVE-2022-32149 mitigation exists: the upstream guard counts only '-' characters but the internal BCP 47 scanner aliases '_' to '-' after the guard check. An unauthenticated attacker can send a crafted Accept-Language header using '_' separators to trigger quadratic-time parsing, consuming excessive CPU and denying authentication to all cluster users. | ||||
| CVE-2026-101029 | 1 Gitea | 1 Gitea | 2026-10-06 | N/A |
| Gitea's repository migration and pull mirror egress checks could be bypassed with a hostname that returns multiple DNS answers, because the address that was validated was not necessarily the address Git later connected to. A low-privileged user who can create migrations or mirrors could direct the server to internal services, reading from and writing to reachable internal Git or HTTP endpoints. Content from internal responses could additionally be disclosed through migration and mirror error messages. | ||||
| CVE-2026-70414 | 2026-10-06 | 5.5 Medium | ||
| Dell Command | Configure (DCC), versions prior to 5.2.3.35, contain a Plaintext Storage of Password vulnerability. A low privileged attacker with local access could potentially exploit this vulnerability, leading to Information Disclosure. | ||||
| CVE-2026-106511 | 2026-10-06 | N/A | ||
| MultiversX's multisig-improved (repository: mx-multisig-and-modules) reference implementation of their on-chain multisig smart contract system contains a vulnerability where a missing independent authorization check allows any account with the Proposer role to perform explicitly barred actions. This vulnerability allows the Proposer role to move funds alone, draining 100% of a contract's EGLD/ESDT balance in two transactions with zero signatures. | ||||
| CVE-2026-76743 | 2026-10-06 | 9.8 Critical | ||
| A vulnerability have been identified in the management interface of AOS-S that could potentially allow an unauthenticated remote attacker to circumvent existing authentication controls if certain preconditions outside of the attacker's control are met. Successful exploitation could allow an attacker to gain unauthorized access to the affected system. | ||||
| CVE-2026-76744 | 2026-10-06 | 9.8 Critical | ||
| Buffer overflow vulnerabilities exist in the affected interface of AOS-S. Successful exploitation could allow an unauthenticated remote attacker to execute arbitrary code. | ||||
| CVE-2026-76746 | 2026-10-06 | 9.3 Critical | ||
| An unauthenticated buffer overflow vulnerability exists in AOS-S. Successful exploitation could allow an unauthenticated adjacent attacker to expose sensitive memory contents and cause a denial of service on the affected device. | ||||
| CVE-2026-76748 | 2026-10-06 | 8.8 High | ||
| A privilege escalation vulnerability exists in the API of AOS-S. Successful exploitation could allow an authenticated read-only user to escalate their privileges and gain administrative access to the affected system. | ||||
| CVE-2026-76749 | 2026-10-06 | 6.5 Medium | ||
| A sensitive information disclosure vulnerability exists in AOS-S. Successful exploitation could allow an unauthenticated remote attacker to access sensitive information. | ||||
| CVE-2026-106461 | 1 Backstage | 2 Backstage, Plugin-scaffolder-backend | 2026-10-06 | 4.3 Medium |
| Backstage is an open framework for building developer portals. Prior to 4.1.0, the @backstage/plugin-scaffolder-backend package is affected by incorrect authorization in scaffolder task listing. An authenticated internal user may be able to view metadata for scaffolder tasks outside the visibility intended by a deployment's permission policy. Stored task secrets are not included in the affected response, and no integrity or availability impact was identified. This issue is fixed in version 4.1.0. | ||||
| CVE-2026-105207 | 1 Zitadel | 1 Zitadel | 2026-10-06 | 9.8 Critical |
| ZITADEL 3.0.0 through 3.4.15 and 4.0.0 before 4.17.3 creates links between user accounts and external identity providers without verifying a primary factor or the caller's permission, including on identify-only Login V2 sessions and via the User Service V2 AddIDPLink endpoint. An unauthenticated attacker knowing a victim's login name can bind their own external IdP identity to the victim's account and then sign in as the victim. | ||||
