Cache-Poisoning

A DNSSEC validating resolver, specifically BIND 9 versions within the ranges 9.11.0-9.18.50, 9.20.0-9.20.24, 9.21.0-9.21.23, and their S1 variants, is vulnerable to a denial-of-service attack where an attacker can launch a random subdomain attack against a DNSSEC-signed zone by sending queries faster than the resolver can perform validation, leading to runaway memory usage and potentially exceeding configured limits by orders of magnitude.

A vulnerability in Directus allows for an authorization bypass when response caching is enabled, leading to cross-share confidentiality breaches where sensitive data scoped for one share can be accessed by another share token holder or anonymous users due to an unsegmented cache key.

An authenticated remote attacker can exploit multiple vulnerabilities in Eclipse Jetty to achieve arbitrary code execution, bypass security measures, or perform an HTTP cache poisoning attack, necessitating immediate patching and enhanced monitoring of Jetty instances.

A vulnerability in Unbound allows an attacker from an adjacent network to manipulate the cache, potentially leading to domain hijacking.

Netty's DNS codec fails to enforce RFC 1035 domain name constraints, leading to potential DNS cache poisoning, denial-of-service, and domain validation bypass through null byte injection, overlength labels, silent truncation, and unbounded memory allocation.

The experimental `hickory-recursor` crate in Hickory DNS is vulnerable to cross-zone cache poisoning due to storing DNS records keyed by record name/type instead of query, enabling an attacker to redirect queries for a victim zone to an attacker-controlled nameserver.

A vulnerability in versions prior to 0.2.86 of the act project allows remote attackers to create arbitrary caches, potentially leading to remote code execution within Docker containers by poisoning predicted cache keys.

An anonymous remote attacker can exploit multiple vulnerabilities in Red Hat JBoss Enterprise Application Platform to cause a denial-of-service condition, manipulate data, and conduct further attacks such as cache poisoning and session hijacking.

Open WebUI versions up to 0.8.12 are vulnerable to cross-instance cache poisoning when multiple instances share a Redis backend, allowing an attacker with admin access on one instance to overwrite cache values used by other instances, leading to data exfiltration and prompt injection attacks.

A vulnerability in FlightPHP core versions before 3.18.1 allows attackers to override HTTP methods via the `X-HTTP-Method-Override` header or `_method` parameter, leading to CSRF escalation, middleware bypass, and cache poisoning.

ORY Oathkeeper before 26.2.0 is vulnerable to authentication bypass (CVE-2026-33496) due to cache key confusion in the `oauth2_introspection` authenticator, allowing attackers with a valid token to bypass authentication by reusing it with different introspection URLs.
