CVE-2025-22868

Unexpected memory consumption during token parsing in golang.org/x/oauth2

CVSS 7.5 HIGHEPSS 0.8%CWE-1286
In short

An attacker can send a specially crafted token that makes the OAuth2 library consume excessive memory while trying to parse it, potentially causing the application to slow down or crash.

Technical detail

The golang.org/x/oauth2 library fails to properly validate token structure during parsing, allowing an attacker to supply a malformed token that triggers unbounded memory allocation. This denial-of-service condition occurs without authentication requirements, impacting any application using the vulnerable library version.

Summary generated and translated by AI from the official description.
An attacker can pass a malicious malformed token which causes unexpected memory to be consumed during parsing.
