CVE-2026-87802: Apache Syncope: SRA OAuth2 JWT signature verification bypass

Low-severity CVE-2026-87802 in Apache Syncope SRA allows JWT signature forgery in OAuth 2.0 setups without JWKS URI.

CVE-2026-87802 is a low-severity improper cryptographic signature verification flaw in Apache Syncope SRA affecting versions 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. When SRA is configured for OAuth 2.0 without a JWKS set URI assigned, an attacker can forge tokens, bypassing JWT signature verification.

CVE-2026-78330: Apache Syncope: Privilege escalation for admin user via JWT authentication

Apache Syncope allows privilege escalation for an admin user via misconfigured internal JWT JWKS authentication settings, versions through 4.1.2.

CVE-2026-78330 is a moderate-severity incorrect privilege assignment vulnerability in Apache Syncope's syncope-core-spring module. When the configured JWKS settings for internal JWT authentication are misconfigured, an admin user can escalate privileges. 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.

The Machine With Many Faces: Post-Exploitation Identity Misuse in SPIFFE/SPIRE

Unit 42 demonstrates that root access on a Kubernetes node lets attackers spoof SPIFFE/SPIRE attestation and harvest co-located workloads' SVIDs.

Palo Alto Networks Unit 42 describes post-exploitation techniques in which an attacker with root on a compromised Kubernetes node spoofs Linux cgroup metadata used by the SPIRE agent during workload attestation, tricking it into issuing a co-located workload's SPIFFE Verifiable Identity Document to an attacker-controlled process. The research shows the core trust assumption of machine-identity systems—that the node is trusted—collapses once root is obtained, exposing all cryptographic identities scoped to that node. Unit 42 released an open-source tool, Spooffe, for defenders to test identity exposure, and notes the technique has not been observed exploited in the wild.
