  • Probability of exploitation in the next 30 days: 0.45% (FIRST EPSS).
  • Anyone who can reach it over the internet can trigger it. No account or password is required. A user must open a link or visit a page. No special conditions are required; it is repeatable.

Generated automatically from the record's data: CVSS (NVD and CNA), CISA KEV and SSVC, FIRST EPSS, exploit sources, fixed versions. How we calculate it

Primary sources: NVD · CVE.org · FIRST EPSS

Vault Community Edition and Vault Enterprise experienced a regression where functionality that HMAC’d sensitive headers in the configured audit device, specifically client tokens and token accessors, was removed. This resulted in the plaintext values of client tokens and token accessors being stored in the audit log. This vulnerability, CVE-2024-8365, was fixed in Vault Community Edition and Vault Enterprise 1.17.5 and Vault Enterprise 1.16.9.
