Java-springboot-codebase: Absolute Path Traversal
CVE-2025-46822 is a high-severity absolute path traversal vulnerability in Java-springboot-codebase from OsamaTaher, with a CVSS 4.0 base score of 7.7 out of 10. It can be exploited remotely over the network by an unauthenticated attacker, without any action from a user. Affected Java-springboot-codebase versions: < c835c6f7799eacada4c0fc77e0816f250af01ad2. The record does not name a fixed version, so check the vendor advisory. There is no confirmed exploitation so far. EPSS estimates a 4.07% chance of exploitation within 30 days, which is in the top 9.15% of all scored CVEs.
High severity with no evidence of exploitation so far.
What to do
- Check which version of Java-springboot-codebase you run against the affected versions below, and install the vendor's latest release.
- Read the advisory on github.com for workarounds and exact fixed builds.
- Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.

Official description
OsamaTaher/Java-springboot-codebase is a collection of Java and Spring Boot code snippets, applications, and projects. Prior to commit c835c6f7799eacada4c0fc77e0816f250af01ad2, insufficient path traversal mechanisms make absolute path traversal possible. This vulnerability allows unauthorized access to sensitive internal files. Commit c835c6f7799eacada4c0fc77e0816f250af01ad2 contains a patch for the issue.

The underlying weakness: Absolute Path Traversal
The product uses external input to construct a pathname that should be within a restricted directory, but it does not properly neutralize absolute path sequences such as /abs/path that can resolve to a location that is outside of that directory.
How developers prevent this class of flaw
- Inputs should be decoded and canonicalized to the application's current internal representation before being validated (CWE-180). Make sure that the application does not decode the same input twice (CWE-174). Such errors could be used to bypass allowlist validation schemes by introducing dangerous inputs after they have been checked.
- Use an application firewall that can detect attacks against this weakness. It can be beneficial in cases in which the code cannot be fixed (because it is controlled by a third party), as an emergency prevention measure while more comprehensive software assurance measures are applied, or to provide defense in depth.
Timeline
- CVE record published.
- CISA published its SSVC assessment (exploitation: poc, automatable: yes, technical impact: partial).
- Record last changed materially (score, affected products, status or references).
