CVE-2026-11923
HighCVSS 7.4Exploitation Probability (EPSS)
Low risk16th percentile - higher than 16% of all known CVEs
Summary
IBM Security Verify Access and IBM Verify Identity Access (including container version) Reverse Proxy in certain configurations may provide weaker than expected cryptographic validation of user supplied data.
Risk Assessment
Weaker cryptographic validation may allow an attacker to manipulate data or bypass security mechanisms, potentially leading to data integrity compromise.
Recommendation
Update the reverse proxy configuration according to IBM recommendations and apply available security patches.
