CVE-2026-107686 Vulnerability Summary

CVE-2026-107686: The Gitea web handlers for adding and removing reactions on issues and comments did not refuse locked issues for users without write access, although the API did. A signed-in user who could read an issue could therefore add or remove reactions on a locked issue and its comments, bypassing the interaction restriction of the lock. Only reactions were affected; no content could be changed.

Assessing the Risk of CVE-2026-107686

Access Complexity Graph

The exploitability of CVE-2026-107686 depends on two key factors: attack complexity (the level of effort required to execute an exploit) and privileges required (the access level an attacker needs).

Exploitability Analysis for CVE-2026-107686

No exploitability data is available for CVE-2026-107686.

Understanding AC and PR

A lower complexity and fewer privilege requirements make exploitation easier. Security teams should evaluate these aspects to determine the urgency of mitigation strategies, such as patch management and access control policies.

Attack Complexity (AC) measures the difficulty in executing an exploit. A high AC means that specific conditions must be met, making an attack more challenging, while a low AC means the vulnerability can be exploited with minimal effort.

Privileges Required (PR) determine the level of system access necessary for an attack. Vulnerabilities requiring no privileges are more accessible to attackers, whereas high privilege requirements limit exploitation to authorized users with elevated access.

CVSS Score Breakdown Chart

Above is the CVSS Sub-score Breakdown for CVE-2026-107686, illustrating how Base, Impact, and Exploitability factors combine to form the overall severity rating. A higher sub-score typically indicates a more severe or easier-to-exploit vulnerability.

CIA Impact Analysis
