CVE-2026-1491
MediumCVSS 5.3Exploitation Probability (EPSS)
Low risk31th percentile - higher than 31% of all known CVEs
Summary
IBM Security Verify Access and IBM Verify Identity Access contain a vulnerability due to inconsistent interpretation of HTTP requests by a reverse proxy. This could allow a remote attacker to access sensitive information.
Risk Assessment
An attacker could exploit the HTTP parsing inconsistency to bypass access controls and disclose credentials or other sensitive data.
Recommendation
Update IBM Security Verify Access / IBM Verify Identity Access to the latest patched version and review reverse proxy configuration.
