CVE-2026-86465: Apache Airflow Akeyless provider: Akeyless secrets backend: team-scope guard bypass via user-controlled key
Apache Airflow Akeyless provider before 0.3.1 lets DAG authors bypass team-scope guards and read other teams' secrets.
CVE-2026-86465 (moderate) affects apache-airflow-providers-akeyless before 0.3.1. The Akeyless secrets backend's team-scope guard can be bypassed with a user-controlled key: in multi-team deployments, a DAG author scoped to one team can supply a Variable key containing a path separator that resolves a secret belonging to another team.

CVE-2026-86466: Apache Airflow FAB provider: FAB Authentik provider: id_token issuer/audience not validated
Apache Airflow FAB provider before 3.9.0 skips issuer/audience validation on Authentik id_tokens, allowing tokens minted for other clients to authenticate to Airflow.
CVE-2026-86466 affects apache-airflow-providers-fab before 3.9.0. The Authentik OAuth path in the FAB auth manager does not validate the issuer or audience claims of accepted id_tokens. An attacker holding a token minted by the same Authentik identity provider for a different client application can present it to Airflow and be authenticated. Severity is rated moderate by the reporter.

CVE-2026-82310: Apache Airflow FAB provider: FAB auth manager: deactivated users retain and renew Core API JWT access
Apache Airflow FAB provider 2.0.0-3.8.x lets deactivated users keep unexpired Core API JWTs and mint replacements indefinitely.
CVE-2026-82310 affects apache-airflow-providers-fab versions 2.0.0 before 3.9.0. Deactivating a user account does not stop tokens issued before deactivation. While password authentication correctly rejects the disabled account, the Core API continues to accept an existing unexpired token naming it and lets that token mint a replacement. Severity is rated moderate.

CVE-2026-76187: Apache Airflow Keycloak provider: Any realm client's credentials mint an Airflow session JWT
Apache Airflow Keycloak provider before 0.10.0 lets any confidential client's credentials in the realm mint an Airflow session JWT.
CVE-2026-76187 affects apache-airflow-providers-keycloak before 0.10.0. The unauthenticated token endpoint accepts a client-credentials grant for any confidential client registered in the Keycloak realm, not only the client configured for Airflow. No allowlist restricts which client ids may authenticate, so credentials of an unrelated application can obtain an Airflow session JWT. Severity is rated moderate.

CVE-2026-84501: Apache ZooKeeper: Operational log forgery via newline injection in EnsembleAuthenticationProvider
Unauthenticated attackers can forge Apache ZooKeeper operational log lines via newline injection in crafted ensemble authentication requests.
CVE-2026-84501 (moderate severity) affects Apache ZooKeeper 3.9.0-3.9.5 and 3.8.0-3.8.6. An unauthenticated attacker can inject arbitrary fake log lines into the operational log by sending a crafted add_auth("ensemble", ...) request containing newline characters. The forged entries could mislead operators or corrupt log-based monitoring and forensics.

CVE-2026-84439: Apache ZooKeeper: Audit log injection via unsanitized output from multiple sources
Apache ZooKeeper audit logs are vulnerable to arbitrary field injection by unauthenticated attackers via tab characters in digest auth requests.
CVE-2026-84439 (important severity) affects Apache ZooKeeper 3.9.0-3.9.5 and 3.8.0-3.8.6 when audit logging is enabled (zookeeper.audit.enable=true). An unauthenticated attacker can inject arbitrary fields into the audit log by sending a digest authentication request with embedded tab characters, undermining audit trail integrity and potentially enabling log-analysis evasion or spoofing.

CVE-2026-59969: Apache ZooKeeper: Improper validation of certificate with host mismatch in FIPS mode
CVE-2026-59969: Apache ZooKeeper quorum TLS skips peer hostname verification in FIPS-mode deployments, enabling potential server-to-server impersonation.
Apache ZooKeeper versions 3.8.0-3.8.6 and 3.9.0-3.9.5 fail to enforce peer hostname verification for quorum TLS when FIPS mode is enabled with sslQuorum, zookeeper.fips-mode, and hostname verification settings turned on. The flaw is rated important and could allow an attacker to impersonate a quorum peer via certificate host mismatch. Users should upgrade to fixed versions.

CVE-2026-59739: Apache ZooKeeper: Information disclosure via SetWatches reconnect replay
CVE-2026-59739: Apache ZooKeeper missing ACL check in SetWatches reconnect replay lets attackers discover ACL-restricted znode paths.
Apache ZooKeeper versions 3.8.0-3.8.6 and 3.9.0-3.9.5 contain a critical information disclosure (CVE-2026-59739) caused by a missing ACL check during SetWatches reconnect replay. An attacker can register exists-watches on non-existent paths and reconnect after those paths are created, revealing the existence of ACL-restricted paths. The issue is fixed in patched releases.

CVE-2026-86460: Apache Syncope: Cypher Injection via FIQL Search on Neo4j Persistence
Apache Syncope's Neo4j persistence layer permits Cypher injection via certain FIQL search expressions, affecting versions through 3.0.16, 4.0.7, and 4.1.2.
CVE-2026-86460 is a moderate-severity Cypher injection in Apache Syncope's syncope-core-persistence-neo4j module, triggered when processing some FIQL search strings. Affected versions are 3.0.0-M0 through 3.0.16, 4.0.0-M0 through 4.0.7, and 4.1.0-M0 through 4.1.2. No exploitation is reported; upgrade to fixed releases is advised.
22
CVE-2026-78318: Apache Syncope: Unauthenticated reflected XSS in Console and Enduser
Apache Syncope Console and Enduser UIs suffer unauthenticated reflected XSS via notification messages, affecting versions 4.0.4 through 4.1.2.
CVE-2026-78318 is a moderate-severity cross-site scripting flaw in Apache Syncope's syncope-client-idrepo-common-ui module. The notification message, optionally shown by the Console and Enduser UIs, is improperly neutralized, enabling unauthenticated reflected XSS. Affected versions are 4.0.4 through 4.0.7 and 4.1.0-M0 through 4.1.2; no exploitation is reported.
25
CVE-2026-80352: Apache Camel K: Camel K Master trait serviceAccountName YAML injection lets CR author apply arbitrary objects
Apache Camel K CVE-2026-80352 lets CR authors inject arbitrary Kubernetes objects via Master trait serviceAccountName YAML injection.
Apache disclosed a critical YAML injection vulnerability (CVE-2026-80352, improper control of code generation) in Apache Camel K's Master trait serviceAccountName setting. An authorized custom resource author can inject arbitrary Kubernetes objects, potentially enabling unauthorized resource manipulation. Affected versions are 2.0.0 before 2.9.3 and 2.10.1 before 2.10.2; fixes are available in 2.9.3 and 2.10.2.
35
CVE-2026-75156: Apache Airflow FAB provider: FAB Azure AD OAuth: id_token issuer/audience not validated — cross-tenant authentication bypass
Apache Airflow FAB provider flaw (CVE-2026-75156) lets attackers bypass Azure AD OAuth token validation via unvalidated issuer and audience claims.
Apache Airflow FAB provider versions 3.7.3 through 3.8.0 do not validate the issuer or audience of Azure AD id_tokens during OAuth login, enabling cross-tenant authentication bypass. The issue affects deployments where the FAB auth manager is configured with Azure AD as an OAuth provider. A fix is available in version 3.8.1. Severity is rated moderate.

CVE-2026-41870: Apache Nutch: Unauthenticated remote code execution (RCE) via JEXL injection in Nutch Server (Nutch REST API)
Apache fixed CVE-2026-41870, a critical unauthenticated RCE via JEXL injection in Nutch Server's REST API affecting versions 1.11-1.22.
CVE-2026-41870 describes a critical Missing Authorization and Code Injection vulnerability in Apache Nutch Server (the Nutch REST API), enabling unauthenticated remote code execution via JEXL injection. Affected versions are Apache Nutch 1.11 through 1.22. Users are recommended to upgrade to version 1.23, which removes the Nutch Server; users who cannot upgrade must apply mitigations.
