Assigner: Gitea Limited

Description

When processing issue and comment bodies, Gitea scanned the entire preceding text for action keywords such as "closes" or "fixes" once per Markdown link, giving processing time quadratic in the input size. An authenticated user able to submit issue or comment content could send a crafted body of about 1 MB that keeps a CPU core busy for several minutes while holding a database transaction open.

CWE ID	Description
CWE-407	An algorithm in a product has an inefficient worst-case computational complexity that may be detrimental to system performance and can be triggered by an attacker, typically using crafted manipulations that ensure that the worst case is being reached.

Attack-Flow Graph

Executive Summary

This vulnerability involves Gitea scanning the entire preceding text for action keywords like 'closes' or 'fixes' once per Markdown link. This creates a processing time that grows quadratically with input size. An attacker could exploit this by submitting a large crafted body (about 1 MB) to keep a CPU core busy for several minutes while holding a database transaction open.

Detection Guidance

This vulnerability is related to inefficient text processing in Gitea when handling issue or comment bodies with Markdown links. Detection involves checking for unusually high CPU usage during issue or comment processing, especially with large text inputs. Monitor Gitea logs for slow database transactions or timeouts during these operations.

Impact Analysis

If you are a Gitea instance administrator, this vulnerability could lead to denial-of-service by consuming excessive CPU resources and blocking database transactions. Users submitting large issue or comment bodies may cause performance degradation or system unavailability.

Compliance Impact

This vulnerability does not directly affect compliance with GDPR, HIPAA, or similar standards as it relates to a performance issue in Gitea's text processing rather than data protection or privacy violations.

Mitigation Strategies

Update Gitea to the latest patched version to address the quadratic processing time issue in issue and comment bodies.
