CVE-2026-92984
HighCVSS 8.1Exploitation Probability (EPSS)
Low risk17th percentile - higher than 17% of all known CVEs
Summary
HUBzero CMS through 2.2.32 accepts session identifiers from query strings and request variables instead of cookies alone, allowing unauthenticated attackers to fixate victim sessions. Attackers can obtain a valid session identifier, send victims a crafted link containing it, and replay the identifier after the victim authenticates to hijack their account and access.
Risk Assessment
Possible hijacking of user accounts, including administrators, via session fixation attacks, leading to unauthorized access to data and system functions.
Recommendation
Update HUBzero CMS to a version later than 2.2.32 and enforce accepting session identifiers only from cookies.
