Summary
IBM WebSphere Application Server (WAS) 6.0 through 6.0.2.43, 6.1 before 6.1.0.43, 7.0 before 7.0.0.23, and 8.0 before 8.0.0.3 computes hash values for form parameters without restricting the ability to trigger hash collisions predictably, which allows remote attackers to cause a denial of service (CPU consumption) by sending many crafted parameters.
Patch / fix
Exploit prediction
2.27% chance of exploitation in the next 30 days, higher than 83% of all scored CVEs (FIRST EPSS, 2026-11-09).

Fencer Intel keeps one entry per vulnerability: the CVE id wins, then GHSA, and records that alias each other are merged, except that two CVEs always keep separate entries. The same data is available as JSON.
