EchelonGraph scoreMEDIUM confidence

This critical-severity CVE scores 9.3 under a secondary CVSS source (NVD's own analysis pending). EPSS exploit probability: 0.3%, top 77% of all CVEs by exploit prediction. GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).

No vendor fix yet — apply a workaround or compensating control (WAF / firewall / segmentation) and watch for a patch.

The ‘/password/guardarClau/recover’ endpoint accepts the ‘usuariId’ parameter, which specifies the account whose password is to be changed. The JWT token for the recovery process is not validated against the user specified in that parameter. An unauthenticated attacker could manipulate the identifier and reset the password for any account, including administrative accounts, which could allow them to take control of the account.
