CVE-2026-73576 Aug 13, 15:26 MEDIUM PATCH This Month

JWT signing secret forgery in Zimbra Collaboration before 10.1.17 stems from the zimbraDocumentEditingJwtSecret being generated with an insecure pseudo-random number generator, yielding insufficient entropy. An authenticated attacker who captures a JWT token from the OnlyOffice integration can perform offline brute-force to recover the signing secret, then mint arbitrary forged tokens - enabling impersonation or unauthorized document access within the OnlyOffice workflow. No public exploit code and no CISA KEV listing have been identified at time of analysis; exploitation requires multi-step conditions including a valid Zimbra account and captured JWT traffic.

CVE-2026-6420 May 06, 10:19 PyPI MEDIUM PATCH GHSA This Month

Keylime verifier uses a hardcoded challenge nonce instead of cryptographically random values for TPM quote attestation, allowing local attackers with root access on enrolled machines to capture valid quotes and replay them to bypass detection after system compromise. The vulnerability affects only push-model deployments and requires root privileges on the monitored endpoint; exploitation enables information disclosure and system integrity evasion with CVSS 6.3 severity.

CVE-2025-32056 Jan 22, 16:16 MEDIUM This Month

The anti-theft protection mechanism can be bypassed by attackers due to weak response generation algorithms for the head unit. It is possible to reveal all 32 corresponding responses by sniffing CAN traffic or by pre-calculating the values, which allow to bypass the protection. [CVSS 4.0 MEDIUM]
