New Interrupt Injection Attack Can Bypass Spectre v2 Defenses on Intel and AMD CPUs

An unprivileged Linux program can time a hardware interrupt to land in the gap between a processor sanitizing its branch predictor and the kernel using it, re-poisoning the predictor after the defense has run. MIT CSAIL researchersDaniël Trujillo and Mengjia Yan named the technique INTERRUPT...

CVE-2025-49506

APR-util versions 1.6.3 and earlier expose a timing-side-channel vulnerability in apr_password_validate(), leaking information about hashes or passwords on platforms lacking crypt() (Windows, BeOS, NetWare, Android). The issue is fixed in version 1.6.4. Affected component: APR-util password valid...

CVE-2026-70437

Jenkins Webhook Secret Credentials Provider Plugin 16.v0cfaf0215cf5 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 bear...

PYSEC-2026-3552 cryptography: PKCS#7 EnvelopedData decryption exposes a Bleichenbacher oracle through distinguishable errors and timing

Summary pkcs7decryptder, pkcs7decryptpem, and pkcs7decryptsmime 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...

Timing Attack

Overview Affected versions of this package are vulnerable to Timing Attack in the pkcs7decryptder, pkcs7decryptpem, and pkcs7decryptsmime functions. An attacker can obtain sensitive information about the outcome of RSA decryption operations by submitting crafted EnvelopedData and analyzing error...

CVE-2026-47746

Misskey is an open source, federated social media platform. Versions 12.37.0 and later, but prior to 2026.5.4, are vulnerable to timing attacks during JSON-LD signature validation and the compaction process. Because the JSON-LD parsing context is not shared between signature verification and...

CVE-2026-47746 Misskey: JSON-LD signature validation + compaction is vulnerable to timing attacks

Misskey is an open source, federated social media platform. Versions 12.37.0 and later, but prior to 2026.5.4, are vulnerable to timing attacks during JSON-LD signature validation and the compaction process. Because the JSON-LD parsing context is not shared between signature verification and...

CVE-2026-69247 cryptography: PKCS#7 EnvelopedData decryption exposes a Bleichenbacher oracle through distinguishable errors and timing

cryptography is a package designed to expose cryptographic primitives and recipes to Python developers. From 44.0.0 until 50.0.0, pkcs7decryptder, pkcs7decryptpem, and pkcs7decryptsmime reported the outcome of decrypting a RecipientInfo's encryptedKey in several distinguishable ways, one of which...

CVE-2026-8794

PaperCut 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...

CVE-2026-8794 PaperCut NG/MF: User enumeration via timing attack

PaperCut 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...

CVE-2026-8794

PaperCut NG/MF is affected by a timing-based user enumeration vulnerability in its authentication component. An unauthenticated remote attacker can detect whether a login target exists by measuring response times, since the system only performs a password hash comparison after confirming a valid ...

CVE-2026-45376

Decidim is a participatory democracy framework. Prior to 0.30.9, from 0.31.0 before 0.31.5, and in 0.32.0.rc1 before 0.32.0.rc2, the GET /admin/organization/users search interpolates params:term into raw Arel.sql ORDER BY similarity expressions before sanitization, allowing an authenticated...

CVE-2026-45376

CVE-2026-45376 affects Decidim admin user search. The vulnerability occurs when untrusted input from params[:term] is interpolated into raw SQL in ORDER BY clauses, allowing an authenticated organization administrator to cause time-based blind SQL injections via the sort expression. Affected path...

Token Content Access - Moderately critical - Access bypass - SA-CONTRIB-2026-090

The Token Content Access module enables site administrators to provide access to content using access tokens. The module does not sufficiently protect access token comparison in some cases. This could allow a persistent attacker to use a timing attack to guess a valid access token and bypass acce...

hono: Hono - Timing Attack in basicAuth and bearerAuth Middleware

A flaw was found in Hono. This vulnerability, a timing attack, exists in the basicAuth and bearerAuth middlewares due to a non-constant-time string comparison. A remote attacker could exploit the early termination of string equality checks to infer valid credentials by precisely measuring respons...
