Fiber 安全漏洞

Fiber is an open-source web framework written in Go. Versions of Fiber 3.1.0 and earlier contain security vulnerabilities. These vulnerabilities stem from the default key generator used in the caching middleware, which only uses the request path without including the query string. As a result,...

GHSA-35HP-HQMV-8QG8 Fiber's cache middleware default key generator ignores query string, causing response mix-up across distinct query parameters

Summary Fiber cache middleware's default key generator uses only c.Path and does not include the query string. As a result, requests like /?id=1 and /?id=2 can map to the same cache key and share the same cached response. This can cause response mix-up cache poisoning-like behavior for endpoints...

Use of Cache Containing Sensitive Information

Overview Affected versions of this package are vulnerable to Use of Cache Containing Sensitive Information due to the default KeyGenerator process in the cache middleware not including query parameters when generating cache keys. An attacker can access or cause exposure of user-specific or...

CVE-2026-41131

A flaw was found in OpenFGA, an authorization and permission engine. When certain authorization models use conditions with caching enabled, the system can incorrectly generate the same cache key for different requests. This error causes OpenFGA to reuse an outdated authorization decision,...

Incorrect Authorization

Overview Affected versions of this package are vulnerable to Incorrect Authorization due to improper policy enforcement. An attacker can gain unauthorized access or perform actions with insufficient authorization by exploiting cache key collisions that cause the reuse of cached results from...

OpenFGA 安全漏洞

OpenFGA is an open-source authorization/licensing engine built for developers, inspired by Google Zanzibar. Versions of OpenFGA prior to 1.14.1 contained a security vulnerability. This vulnerability arises from the use of cache conditions in certain scenarios, which may lead to two different chec...

CVE-2026-41131 OpenFGA has Improper Policy Enforcement

OpenFGA is an authorization/permission engine built for developers. Prior to version 1.14.1, in specific scenarios, models using conditions with caching enabled can result in two different check requests producing the same cache key. This could result in OpenFGA reusing an earlier cached result f...

CVE-2026-39972

Mercure is a protocol for pushing data updates to web browsers and other HTTP clients in a battery-efficient way. Prior to 0.22.0, a cache key collision vulnerability in TopicSelectorStore allows an attacker to poison the match result cache, potentially causing private updates to be delivered to...

CVE-2026-39972 Mercure has a Topic Selector Cache Key Collision

Mercure is a protocol for pushing data updates to web browsers and other HTTP clients in a battery-efficient way. Prior to 0.22.0, a cache key collision vulnerability in TopicSelectorStore allows an attacker to poison the match result cache, potentially causing private updates to be delivered to...

CVE-2026-39972

CVE-2026-39972 affects Mercure prior to 0.22.0. A cache key collision in TopicSelectorStore arises from concatenating topicSelector and topic with an underscore, which can produce identical keys for different pairs because both fields may contain underscores. An attacker who can subscribe or publ...

mercure 安全漏洞

Mercure is a real-time data delivery protocol and server implementation developed by Kévin Dunglas as an individual project. Versions of Mercure prior to 0.22.0 contained security vulnerabilities. These vulnerabilities were caused by conflicts in cache keys within the TopicSelectorStore, which...

PT-2026-31661

Impact A cache key collision vulnerability in TopicSelectorStore allows an attacker to poison the match result cache, potentially causing private updates to be delivered to unauthorized subscribers or blocking delivery to authorized ones. The cache key was constructed by concatenating the topic...

OpenFGA's BatchCheck within-request deduplication produces incorrect authorization decisions via list-value cache-key collision

Description In OpenFGA, under specific conditions, BatchCheck calls with multiple checks sent for the same object, relation, and user combination can result in improper policy enforcement. Am I affected? You are affected if you meet the following preconditions: 1. You execute BatchCheck operation...
