GHSA-82J3-HF72-7X93

Reposilite vulnerable to path traversal while serving javadoc expanded files (arbitrary file read) (GHSL-2024-074)

fun findRawJavadocResource(request: JavadocRawRequest): Result<JavadocRawResponse, ErrorResponse> =
   with (request) {
       mavenFacade.canAccessResource(accessToken, repository, gav)
           .flatMap { javadocContainerService.loadContainer(accessToken, repository, gav) }
           .filter({ Files.exists(it.javadocUnpackPath.resolve(resource.toString())) }, { notFound("Resource $resource not found") })
           .map {
               JavadocRawResponse(
                   contentType = supportedExtensions[resource.getExtension()] ?: ContentType.APPLICATION_OCTET_STREAM,
                   content = Files.newInputStream(it.javadocUnpackPath.resolve(resource.toString()))
               )
           }
   }

This issue may lead to Arbitrary File Read on the server. A potential attacker can read some sensitive file, such as reposilite.db, that contains the sqlite database used by Reposilite. This database contains the sensitive information used by Reposilite, including passwords and hashes of issued tokens. Also, the configuration.cdn file can be read, which contains other sensitive properties.

Input manipulates file paths to reach files outside the intended directory, such as configuration or credential files. Typical impact: unauthorized file read or write outside the intended directory.

GHSA-82J3-HF72-7X93 has a CVSS score of 8.2 (High). The vector is network-reachable, no privileges required, and no user interaction. 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 (3.5.12); upgrading removes the vulnerable code path.

Kodem intelligence

Already deployed Kodem?

Normalize (remove all occurrences of /../) the <resource> path parameter before using it when reading the file. For example:

content = Files.newInputStream(it.javadocUnpackPath.resolve(resource.toPath()))

Changing resource.toString() to resource.toPath() is enough here as the com.reposilite.storage.api.Location#toPath method normalizes the string internally.

1. What is GHSA-82J3-HF72-7X93? GHSA-82J3-HF72-7X93 is a high-severity path traversal vulnerability in com.reposilite:reposilite-backend (maven), affecting versions >= 3.3.0, < 3.5.12. It is fixed in 3.5.12. Input manipulates file paths to reach files outside the intended directory, such as configuration or credential files.
2. How severe is GHSA-82J3-HF72-7X93? GHSA-82J3-HF72-7X93 has a CVSS score of 8.2 (High). 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 com.reposilite:reposilite-backend are affected by GHSA-82J3-HF72-7X93? com.reposilite:reposilite-backend (maven) versions >= 3.3.0, < 3.5.12 is affected.
4. Is there a fix for GHSA-82J3-HF72-7X93? Yes. GHSA-82J3-HF72-7X93 is fixed in 3.5.12. Upgrade to this version or later.
5. Is GHSA-82J3-HF72-7X93 exploitable, and should I be worried? Whether GHSA-82J3-HF72-7X93 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-82J3-HF72-7X93 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-82J3-HF72-7X93? Upgrade com.reposilite:reposilite-backend to 3.5.12 or later.
