NVD Source

Risk Analysis

AgileConfig versions before 1.6.8 use a hardcoded JWT secret, allowing remote attackers to forge tokens and gain administrative access. This critical flaw carries a 9.8 CVSS score due to the ease of unauthorized privilege escalation.

No public exploit is known, and the vulnerability is not in the CISA KEV catalog. It is remotely exploitable.

Recommended Action

Upgrade to AgileConfig version 1.6.8 or later and ensure that all secret keys are properly rotated.

Generated by the CTIWATCH analysis pipeline from this CVE's metadata (CVSS, EPSS, KEV status, exploit intelligence). Verify against vendor advisories before acting.

Technical Analysis

CVE-2022-35540 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.

The vulnerability requires no privileges and no user interaction, making it a prime target for automated exploitation campaigns and worm-like propagation.

A successful exploit results in complete confidentiality breach (data exposure), full integrity compromise (data manipulation), availability disruption (denial of service), with a CVSS base score of 9.8.
