Which packages are affected by GHSA-c558-5gfm-p2r8?

GHSA-c558-5gfm-p2r8 affects the following packages: org.dspace:dspace-jspui (Maven), org.dspace:dspace-jspui (Maven). Ecosystems affected: Maven.

How do I fix GHSA-c558-5gfm-p2r8?

Update org.dspace:dspace-jspui to 5.11 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-c558-5gfm-p2r8 is resolved across your whole dependency graph.

How do I detect GHSA-c558-5gfm-p2r8 in my Maven dependencies?

Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for org.dspace:dspace-jspui. O3's reachability analysis confirms whether the vulnerable code path is actually invoked in your application, so you act on real exposure instead of every transitive match.

How do I mitigate GHSA-c558-5gfm-p2r8 if there is no patch (or I can't update yet)?

If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.

How does O3 Security protect against GHSA-c558-5gfm-p2r8?

O3 pinpoints whether GHSA-c558-5gfm-p2r8 is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.

Is GHSA-c558-5gfm-p2r8 actively exploited in the wild?

No public exploit code has been indexed for GHSA-c558-5gfm-p2r8 yet. This does not mean the vulnerability cannot be exploited — absence of public exploits does not imply safety. Apply the recommended fix and use O3 Security to monitor your exposure.

What is the EPSS score for GHSA-c558-5gfm-p2r8?

GHSA-c558-5gfm-p2r8 has an EPSS (Exploit Prediction Scoring System) score of 0.6%, placing it in the 44th percentile of all CVEs. EPSS is maintained by FIRST.org and estimates the probability that a vulnerability will be exploited in the wild within the next 30 days. This score indicates relatively lower exploitation probability, though the CVSS severity should still guide your patching priority.

When was GHSA-c558-5gfm-p2r8 published, and has it been updated?

GHSA-c558-5gfm-p2r8 was published on August 6, 2022 and was last updated on November 8, 2023. Advisory data evolves as severity scores, affected ranges, and exploit intelligence are revised — always check the latest version of the advisory before acting.

Description

Impact

The JSPUI spellcheck "Did you mean" HTML escapes the data-spell attribute in the link, but not the actual displayed text. Similarly, the JSPUI autocomplete HTML does not properly escape text passed to it. Both are vulnerable to XSS. This vulnerability only impacts the JSPUI.

This vulnerability does NOT impact the XMLUI or 7.x.

Apply the patch to your DSpace

If at all possible, we recommend upgrading your DSpace site based on the upgrade instructions. However, if you are unable to do so, you can manually apply the above patches as follows:

Download the appropriate patch file to the machine where DSpace is running
From the [dspace-src] folder, apply the patch, e.g. git apply [name-of-file].patch
Now, update your DSpace site (based loosely on the Upgrade instructions). This generally involves three steps:
1. Rebuild DSpace, e.g. mvn -U clean package (This will recompile all DSpace code)
2. Redeploy DSpace, e.g. ant update (This will copy all updated WARs / configs to your installation directory). Depending on your setup you also may need to copy the updated WARs over to your Tomcat webapps folder.
3. Restart Tomcat
