CVE-2025-30064: Possibility to generate a session for any user via the "ex:action" parameter after obtaining access to the JWT key
- Severity: high (CVSS 8.8 v4.0)
- Exploited in the wild: not listed in CISA KEV
- EPSS: 0.1% probability of exploitation in the next 30 days
- Public exploit or detection template: none known
- Published: 2025-08-27 · updated 2026-06-17
- Weakness: CWE-347
Description
An insufficiently secured internal function allows session generation for arbitrary users. The decodeParam function checks the JWT but does not verify which signing algorithm was used. As a result, an attacker can use the "ex:action" parameter in the VerifyUserByThrustedService function to generate a session for any user.
