Week 20 – Critical elevation of privilege vulnerability in Azure DevOps
12 – 18 May 2025
A critical elevation of privilege vulnerability has been found in Azure DevOps, published on May 8, 2025, and updated with more details 2 days later on May 10, 2025. It has a CVSS score of 10.0!
It’s not often that a truly critical vulnerability is discovered that reaches the maximum severity rating of 10 on the Common Vulnerability Scoring System. This is one such case.
Microsoft confirmed that this Azure DevOps pipeline token hijacking vulnerability is caused by an issue whereby Visual Studio improperly handles the pipeline job tokens, enabling an attacker to potentially extend their access to a project. According to the company’s official communication:
To exploit this vulnerability, an attacker would first have to have access to the project and swap the short-term token for a long-term one.
To be fair, CVE-2025-29813 is just one of a number of critical vulnerabilities affecting core cloud services that the tech giant has confirmed this week. The good news is that none of them are known to have been exploited in the wild, none have been publicly disclosed, and there’s nothing you can do as a user to protect your environment.
“This vulnerability has already been fully mitigated by Microsoft.” -they say, so there’s no need to worry, we can sleep soundly.
