CVE-2011-1321
Status: ModifiedMedium (6.5)—
The AuthCache purge implementation in the Security component in IBM WebSphere Application Server (WAS) 6.1.0.x before 6.1.0.37 and 7.x before 7.0.0.15 does not purge a user from the PlatformCredential cache, which might allow remote authenticated users to gain privileges by leveraging a group membership specified in an old RACF Object (aka RACO).
CVSS
- Version: 2.0
- Vector: AV:N/AC:L/Au:S/C:P/I:P/A:P
- Base score: 6.5
Exploitation probability (EPSS)
- Probability of exploitation in the next 30 days: 0.97%
- Percentile among all scored CVEs: 61
- Score date: 10/7/2026
EPSS (Exploit Prediction Scoring System, FIRST) estimates how likely a vulnerability is to be exploited in the wild within 30 days. It complements CVSS (impact) and CISA KEV (confirmed exploitation).
