1. [medium] A user with write permissions to a portion of a repository may use the S3 gateway to copy any object in the repository if they know its name.
2. [medium] A user with permission to write any one of tags, branches, or commits on a repository may write all of them.
3. [low] A user with permission to read any one of tags, branches, or commits on a repository may read all of them.
4. [low] A user allowed to list objects in a repository or read repository meta-data may retrieve graveler information about the location on underlying storage of all objects stored in any commit that they can view. If the user additionally has the capability to read underlying storage, they will be able to retrieve metadata associated with all objects in that commit.

GHSA-M836-GXWQ-J2PM has a CVSS score of 5.7 (Medium). The vector is network-reachable, low privileges required, and user interaction required. A CVSS score reflects the worst-case severity of the vulnerability, not your specific exposure. Whether this affects your application depends on whether the vulnerable code is present and reachable in your environment. A fixed version is available (0.53.1); upgrading removes the vulnerable code path.

1. What is GHSA-M836-GXWQ-J2PM? GHSA-M836-GXWQ-J2PM is a medium-severity security vulnerability in github.com/treeverse/lakefs (go), affecting versions < 0.53.1. It is fixed in 0.53.1.
2. How severe is GHSA-M836-GXWQ-J2PM? GHSA-M836-GXWQ-J2PM has a CVSS score of 5.7 (Medium). This score reflects the worst-case severity of the vulnerability, not your specific exposure. Whether it represents real risk in your environment depends on whether the vulnerable code is present and reachable.
3. Which versions of github.com/treeverse/lakefs are affected by GHSA-M836-GXWQ-J2PM? github.com/treeverse/lakefs (go) versions < 0.53.1 is affected.
4. Is there a fix for GHSA-M836-GXWQ-J2PM? Yes. GHSA-M836-GXWQ-J2PM is fixed in 0.53.1. Upgrade to this version or later.
5. Is GHSA-M836-GXWQ-J2PM exploitable, and should I be worried? Whether GHSA-M836-GXWQ-J2PM is exploitable in your environment depends on whether the vulnerable code is present and reachable. A CVSS score is a worst-case rating; it does not account for your specific deployment, configuration, or usage patterns. Kodem, an Intelligent Application Security platform, uses runtime intelligence to show which vulnerabilities actually execute in production, so you can focus on the ones that represent real risk.

6. What actually determines whether GHSA-M836-GXWQ-J2PM is exploitable, and how bad it is? Exploitability and impact are not fixed properties of a CVE. They depend on runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A high CVSS score on a dependency that never runs is not the same as real risk. Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter.
7. How do I fix GHSA-M836-GXWQ-J2PM? Upgrade github.com/treeverse/lakefs to 0.53.1 or later.
