CVE-2026-25834
The Mbed TLS library, specifically versions v3.3.0 up to 3.6.5 and 4.0.0 , is susceptible to an Algorithm Downgrade vulnerability (CVE-2026-25834). This issue allows an attacker to force the use of weaker cryptographic algorithms. Security updates have been released for various distributions to m...

Selection of Less-Secure Algorithm During Negotiation ('Algorithm Downgrade')
Overview Affected versions of this package are vulnerable to Selection of Less-Secure Algorithm During Negotiation 'Algorithm Downgrade' in the TLS 1.3 session resumption logic if the subsequent ClientHello negotiates TLS 1.2 back. An attacker can gain unauthorized access by impersonating a...

Selection of Less-Secure Algorithm During Negotiation ('Algorithm Downgrade')
Overview salt is a new approach to infrastructure management built on a dynamic communication bus. Salt can be used for data-driven orchestration, remote execution for any infrastructure, configuration management for any app stack, and much more. Affected versions of this package are vulnerable t...
Selection of Less-Secure Algorithm During Negotiation ('Algorithm Downgrade')
Overview bthome-ble is a BThome BLE support Affected versions of this package are vulnerable to Selection of Less-Secure Algorithm During Negotiation 'Algorithm Downgrade' due to insufficient enforcement of encryption requirements in the parsebthomev1 and parsebthomev2 functions in...
CVE-2025-11934
Improper input validation in the TLS 1.3 CertificateVerify signature algorithm negotiation in wolfSSL 5.8.2 and earlier on multiple platforms allows for downgrading the signature algorithm used. For example when a client sends ECDSA P521 as the supported signature algorithm the server previously...
CVE-2025-11934 Improper Validation of Signature Algorithm Used in TLS 1.3 CertificateVerify
Improper input validation in the TLS 1.3 CertificateVerify signature algorithm negotiation in wolfSSL 5.8.2 and earlier on multiple platforms allows for downgrading the signature algorithm used. For example when a client sends ECDSA P521 as the supported signature algorithm the server previously...
CVE-2025-11934
CVE-2025-11934 concerns wolfSSL’s TLS 1.3 CertificateVerify signature algorithm negotiation. The vulnerability stems from improper input validation that can downgrade the negotiated signature algorithm (e.g., client supports ECDSA P521 but server accepts and uses ECDSA P256), potentially weakenin...
