Cross-Site Request Forgery (CSRF)

PAC4J is vulnerable to Cross-Site Request Forgery CSRF. The vulnerability is due to weak CSRF token validation relying on hash collisions in String.hashCode, which allows an attacker to forge requests with colliding tokens and perform unauthorized actions without the victim’s consent...

ruby: hash table collisions CPU usage DoS (oCERT-2011-003)

Ruby aka CRuby before 1.8.7-p357 computes hash values without restricting the ability to trigger hash collisions predictably, which allows context-dependent attackers to cause a denial of service CPU consumption via crafted input to an application that maintains a hash table...

ruby: Murmur hash-flooding DoS flaw in ruby 1.9 (oCERT-2012-001)

Ruby aka CRuby 1.9 before 1.9.3-p327 and 2.0 before r37575 computes hash values without properly restricting the ability to trigger hash collisions predictably, which allows context-dependent attackers to cause a denial of service CPU consumption via crafted input to an application that maintains...

PAC4J has a Cross-Site Request Forgery (CSRF) Vulnerability

PAC4J is vulnerable to Cross-Site Request Forgery CSRF. A malicious attacker can craft a specially designed website which, when visited by a user, will automatically submit a forged cross-site request with a token whose hash collides with the victim's legitimate CSRF token. Importantly, the...

CVE-2026-40458

PAC4J is vulnerable to Cross-Site Request Forgery CSRF. A malicious attacker can craft a specially designed website which, when visited by a user, will automatically submit a forged cross-site request with a token whose hash collides with the victim's legitimate CSRF token. Importantly, the...

Plonky3: The sponge construction used to get a hash function from a cryptographic permutation is not collision resistant for inputs of different lengths

Vulnerability Currently, when hashing, if the number of elements to hash is not a multiple of the rate, hashiter pads by elements of the current state. This means that it is possible to create iterators of different lengths which lead to an identical hashed state. Given a simple example using a...

jq: jq: Denial of Service via crafted JSON object causing hash collisions

A flaw was found in jq, a command-line JSON processor. A remote attacker could exploit this vulnerability by providing a specially crafted JSON object. This object leverages a weakness in jq's hashing algorithm, which uses a hardcoded, publicly known seed. By crafting the JSON object to cause has...

Insufficient Entropy

Overview Affected versions of this package are vulnerable to Insufficient Entropy due to insufficient randomness in the hash seed generation process. An attacker can cause excessive CPU consumption by submitting specially crafted XML documents that trigger hash collisions. Remediation Upgrade exp...

CVE-2026-40164

jq is a command-line JSON processor. Before commit 0c7d133c3c7e37c00b6d46b658a02244fdd3c784, jq used MurmurHash3 with a hardcoded, publicly visible seed 0x432A9843 for all JSON object hash table operations, which allowed an attacker to precompute key collisions offline. By supplying a crafted JSO...
