CVE-2025-31479: canonical/get-workflow-version-action is a GitHub composite action to get commit SHA that GitHub Actions reusable workflow was called with. Prior to 1.0.1, if the get-workflow-version-action step fails, the exception output may include the GITHUB_TOKEN. If the full token is included in the exception output, GitHub will automatically redact the secret from the GitHub Actions logs. However, the token may be truncated—causing part of the GITHUB_TOKEN to be displayed in plaintext in the GitHub Actions logs. Anyone with read access to the GitHub repository can view GitHub Actions logs. For public repositories, anyone can view the GitHub Actions logs. The opportunity to exploit this vulnerability is limited—the GITHUB_TOKEN is automatically revoked when the job completes. However, there is an opportunity for an attack in the time between the GITHUB_TOKEN being displayed in the logs and the completion of the job. Users using the github-token input are impacted. This vulnerability is fixed in 1.0.1.
The exploitability of CVE-2025-31479 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).
This vulnerability, CVE-2025-31479, requires a high level of attack complexity and low privileges, making it difficult but not impossible to exploit. Organizations should ensure robust security configurations to mitigate risks.
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.
Above is the CVSS Sub-score Breakdown for CVE-2025-31479, 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.
Below is the Impact Analysis for CVE-2025-31479, showing how Confidentiality, Integrity, and Availability might be affected if the vulnerability is exploited. Higher values usually signal greater potential damage.
