CVE-2026-41263

CVE-2026-41263 affects Traefik’s BasicAuth middleware. A timing side-channel allows an attacker to enumerate valid usernames by measuring response times, because the constant-time fallback secret resolves to an empty string, causing the bcrypt check to short-circuit quickly. Vulnerable versions a...

bouncycastle: BC-JAVA: private key leakage via non-constant time comparisons

A flaw was found in Legion of the Bouncy Castle Inc. BC-JAVA core. A covert timing channel vulnerability, caused by non-constant time comparisons, risks the leakage of private keys in the FrodoKEM implementation. An unauthenticated, remote attacker can potentially exploit this timing discrepancy ...

Important: dovecot

Issue Overview: Doveadm credentials are verified using direct comparison which is susceptible to timing oracle attack. An attacker can use this to determine the configured credentials. Figuring out the credential will lead into full access to the affected component. Limit access to the doveadm ht...

Amazon Linux 2 : dovecot, --advisory ALAS2-2026-3252 (ALAS-2026-3252)

The version of dovecot installed on the remote host is prior to 2.2.36-6. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2-2026-3252 advisory. Doveadm credentials are verified using direct comparison which is susceptible to timing oracle attack. An attacker can us...

I Can't Recognize (Yet): Delayed Rendering to Defeat Visual Phishing Detectors

Phishing webpages are continuously polluting the Web. Plenty of countermeasures have been proposed and the most advanced techniques leverage machine-learning methods that infer whether a webpage is benign or not by inspecting its visual representation. Yet, despite the demonstrated effectiveness ...

Traefik 安全漏洞

Traefik is an open-source reverse proxy and load balancing tool developed by Traefik. Versions prior to Traefik 2.11.43, 3.6.14, and 3.7.0-rc.2 contain security vulnerabilities. These vulnerabilities stem from variables used in the BasicAuth middleware for constant-time comparisons, which are...

Timing Attack

org.springframework.boot, spring-boot-devtools is vulnerable to a timing attack. The vulnerability is due to insecure comparison of the DevTools remote secret, which allows an attacker on the same network to exploit timing differences to guess the secret and potentially achieve remote code...

Timing Attack

Overview Affected versions of this package are vulnerable to Timing Attack via the PKCS7 padding check. An attacker can obtain sensitive information by exploiting timing differences during decryption. Remediation A fix was pushed into the master branch but not yet published. References - GitHub...
