CVE-2026-32716

24
FAUCET Score

CVE-2026-32716 is an Authorization Bypass vulnerability affecting the SciTokens reference library prior to version 1.9.6, where the Enforcer's flawed prefix-based scope path validation allows an authenticated user to access unauthorized sibling paths. Rated Medium with a CVSS score of 6.5, this vulnerability has a network attack vector and low attack complexity, posing a high confidentiality risk. Currently, there is no evidence of active exploitation, and no public exploit code is available in common repositories like Metasploit or ExploitDB. Despite some community discussion, its very low EPSS score and absence from the KEV catalog suggest a low probability of widespread exploitation.
