Security Impact
CVSS: 7.5
The security impact metrics below are parsed directly from the CVSS v3.1 vector string (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:N).
How to Fix CVE-2025-68931
To remediate this vulnerability, upgrade all affected Jervis dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.
<dependency>
<groupId>net.gleske</groupId>
<artifactId>jervis</artifactId>
<version>2.2</version>
</dependency>Run the following command in your project directory to verify that all resolved dependencies use the patched release:
mvn dependency:tree -Dincludes=net.gleskeHow to Check if You Are Affected
To determine whether your Java application is affected by CVE-2025-68931, inspect your build dependencies using the Maven Dependency Plugin:
mvn dependency:tree -Dincludes=net.gleskeAnalyze the terminal output to locate any version of Jervis in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 2.2), your application is affected.
Note: The mvn dependency:tree -Dincludes=net.gleske command inspects the resolved dependency graph declared in your project's POM files; it does not perform automated security scanning or inspect runtime dynamic classpaths. Always verify runtime container classpaths and shaded JARs.
Technical Details
Vulnerability Mechanism & Technical Analysis
This vulnerability is classified under CWE-287: Improper Authentication, where when an actor claims to have a given identity, the product does not prove or insufficiently proves that the claim is correct. In Jervis, software state validation or input boundaries are circumvented during processing.

After asymmetric decryption and before symmetric decryption, a SHA-256 checksum is performed on the metadata and encrypted data. All encrypted data is discarded if the checksum does not match without attempting to decrypt since the encrypted data is assumed invalid. The data stored is GitHub App authentication tokens which will expire within one hour.\n\n### Patches\n\nJervis patch will migrate from `AES/CBC/PKCS5Padding` to `AES/GCM/NoPadding`.\n\nUpgrade to Jervis 2.2.\n\n### Workarounds\n\nNone\n\n### References\n\n- [Padding Oracle Attacks](https://en.wikipedia.org/wiki/Padding_oracle_attack)",
