Not enough EPSS history yet.
Observable Timing Discrepancy in the AMD Vitis Libraries ECDSA secp256k1 component could allow attackers with local access to potentially perform timing analysis or electromagnetic emanation attacks, resulting in high confidentiality and integrity impact due to the exposure of private cryptographic keys.

CVE-2025-495067.5 HIG32.2%
——10APR-util versions 1.6.3 (and earlier) function apr_password_validate() was not constant-time with regards to hashes or passwords comparisons, potentially leaking their content via a side channel timing attack particularly on platforms without crypt() such as Windows, BeOS, NetWare, or Android.
Users are recommended to upgrade to version 1.6.4, which fixes this issue.4dCVE-2026-16731—19.6%
——6OMICRON StationScout before version 3.05 contains a cryptographic timing side-channel vulnerability in the backend authentication mechanism that may allow an unauthenticated attacker to forge valid authentication credentials, bypass authentication and authorization, and impersonate legitimate clients.
An attacker can gain full access to the system configuration, allowing modification, reset, or unauthorized alteration of system parameters or injecting network traffic into the connected network.5dCVE-2026-163158.7 HIG17.4%
——5OMICRON StationGuard before version 4.10 contains a cryptographic timing side-channel vulnerability in the backend authentication mechanism that may allow an unauthenticated attacker to forge valid authentication credentials, bypass authentication and authorization, and impersonate legitimate clients.
An attacker can gain full access to the system configuration, allowing modification, reset, or unauthorized alteration of system parameters.5dCVE-2026-704373.7 LOW6.9%
——2Jenkins Webhook Secret Credentials Provider Plugin 16.v0cfa_f0215cf5 and earlier does not use a constant-time comparison function when checking whether the provided and expected webhook bearer token are equal, potentially allowing attackers to use statistical methods to obtain a valid webhook bearer token.5dCVE-2026-69247—7.2%
——2cryptography is a package designed to expose cryptographic primitives and recipes to Python developers. From 44.0.0 until 50.0.0, pkcs7_decrypt_der, pkcs7_decrypt_pem, and pkcs7_decrypt_smime reported the outcome of decrypting a RecipientInfo's encryptedKey in several distinguishable ways, one of which disclosed the exact length recovered from the RSA operation. The same distinction was also observable by timing. An application that decrypts attacker-supplied EnvelopedData and reflects the outcome gives the attacker a Bleichenbacher oracle against the content-encryption key. Decryption ran as RSA PKCS#1 v1.5 decrypt of encryptedKey, build an AES cipher from the result, then AES-CBC decrypt and PKCS#7 unpad. Invalid RSA padding, a valid padding with a bad key length, a correct length with a wrong key, and the real key each failed or succeeded differently. Case 1 is reachable only where the linked library lacks implicit rejection: OpenSSL 3.0 and 3.1, LibreSSL, and BoringSSL. Exploitation requires a service that auto-decrypts untrusted EnvelopedData matching the victim certificate and answers adaptively at high volume, such as an S/MIME gateway or mail filter. This issue is fixed in 50.0.0.7dCVE-2026-8794—48.8%
——15PaperCut NG/MF contains an observable timing discrepancy in its authentication component. An unauthenticated remote attacker can exploit this vulnerability to perform username enumeration by measuring response times during login attempts. The system executes a password hash comparison only when a valid account is supplied, creating a measurable timing oracle that reveals account existence.8d
