Because the token-submission endpoint (taskReset) also lacks rate limiting, an attacker could in principle send repeated token guesses against a known username and use the timing differences to attempt to recover a valid token, though the vendor rates the practical exploitability as low and no end-to-end network exploit has been demonstrated.\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.","depth":"twilight","depthScore":41,"depthScoreParts":{"impact":41.3,"likelihood":0.1,"exploitation":0,"ransomware":0},"changes":[]}
