phpseclib — non-constant-time X25519 scalar multiplication permits full private-key recovery

The pure-PHP X25519 scalar multiplication in phpseclib is not constant-time. Field addition and subtraction each perform a data-dependent conditional modular reduction, so the cost of each Montgomery-ladder step is a linear function of that step's reduction count which is a quantity determined by...

USN-8719-1: APR-util vulnerabilities

It was discovered that APR-util incorrectly performed password hash comparisons in a way that was not constant-time. An attacker could possibly use this issue to obtain sensitive information. CVE-2025-49506 It was discovered that APR-util incorrectly handled recursive XML element quoting. An...

USN-8719-1 apr-util vulnerabilities

It was discovered that APR-util incorrectly performed password hash comparisons in a way that was not constant-time. An attacker could possibly use this issue to obtain sensitive information. CVE-2025-49506 It was discovered that APR-util incorrectly handled recursive XML element quoting. An...

CVE-2026-59276

Several components in Spring Security compare security-sensitive values using standard string equality String.equals rather than a constant-time comparison. Because String.equals returns as soon as it finds a differing character, the time taken to reject an incorrect value is proportional to the...

CVE-2026-55785

free5GC is an open-source implementation of the 5G core network. Prior to 1.4.5, the AUSF component performs cryptographic authentication comparisons in internal/sbi/processor/ueauthentication.go with ordinary equality helpers. Auth5gAkaComfirmRequestProcedure compares RES and XRES with...

free5GC AUSF uses non-constant-time authentication comparisons and logs XRES* in 5G-AKA

Summary The AUSF component of free5GC compares authentication response values with normal Go equality helpers instead of constant-time cryptographic comparison functions. Two authentication flows are affected in internal/sbi/processor/ueauthentication.go: 1. 5G-AKA confirmation compares RES and...

CVE-2026-55785

free5GC's AUSF component (prior to version 1.4.5) performs 5G-AKA cryptographic authentication comparisons in ue_authentication.go using non-constant-time helpers: strings.EqualFold for RES*/XRES* and bytes.Equal for AT_MAC/XMAC. Additionally, the expected XRES* value is logged at INFO level befo...
