# Searching Opencast may cause a denial of service Advisory record · `GHSA-jh6x-7xfg-9cq2` - **Identifiers:** `GHSA-jh6x-7xfg-9cq2` · `CVE-2024-52797` - **State:** Confirmed - **Severity:** CVSS 6.5 Medium - **Critical:** No - **Weakness (CWE):** [CWE-770](https://cwe.mitre.org/data/definitions/770.html) - **Tags:** [Denial of service](https://agentprime.io/advisories/tag/dos.md) - **Published:** 20 Nov 2024 - **Updated:** 28 Oct 2025 - **Reviewed by a person:** No Published by the GitHub Advisory Database at 20 Nov 2024, 22:46 UTC. agentprime has not analysed this yet, so whether it affects any app is not known. ## Affected packages - `org.opencastproject:opencast-elasticsearch-impl` (Maven): affected `>=11.4, <13.10 || >=14.0, <14.3 || >=15.0, <16.7`; fixed in `13.10`, `14.3`, `16.7` ## Machine-written summary Summary written by Claude Haiku from the source advisory. Not reviewed by a person. > Opencast's Elasticsearch integration in org.opencastproject:opencast-elasticsearch-impl versions 11.4 up to 13.10, 14.0 up to 14.3, and 15.0 up to 16.7 can enter an endless retry loop when a previously accepted search produces an invalid query, filling logs and possibly exhausting disk space. The source does not describe a specific attacker role; the affected endpoints normally require admin or API series view roles, and the problem can be triggered by ordinary administrative searches. Upgrade to 13.10, 14.3, or 16.7 depending on your release line; no workarounds are identified. Written 7 Nov 2026. ## Not analysed yet We haven’t published our analysis of this Advisory yet. Once a person has reviewed it, this page will say what’s vulnerable, what has to be true for your app to be affected, and how to check. ## Severity and exploitation - 6.5 Medium, CVSS 3.1: `CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H`, from CNA (GitHub_M) - **CISA KEV:** Not listed. - **EPSS:** 0.0092, the 60th percentile, on 14 Nov 2026: FIRST’s estimate of the chance of exploitation in the next 30 days. ## Timeline - 31 Oct 2026, 15:10 UTC: First seen by agentprime - 31 Oct 2026, 15:10 UTC: [Confirmed by OSV](https://osv.dev/vulnerability/GHSA-jh6x-7xfg-9cq2) ## Sources - [GitHub Advisory Database: GHSA-jh6x-7xfg-9cq2](https://github.com/advisories/GHSA-jh6x-7xfg-9cq2) - [OSV: GHSA-jh6x-7xfg-9cq2](https://osv.dev/vulnerability/GHSA-jh6x-7xfg-9cq2) - - - - - - - Facts on this page come from the GitHub Advisory Database (CC-BY 4.0), OSV and the other sources listed, as published. We don’t reproduce full advisory descriptions, which can contain exploit code. ## Check whether this affects you A Match means an installed version is in the affected range above. Most don’t affect the app; agentprime hasn’t analysed this one yet. - With the agentprime MCP server (), ask your agent to check the project: `check_lockfile` sends a lockfile, `check_packages` a list of installed packages, and both return the Matches and the upgrades that clear them. `get_advisory` returns this record. Setup: - In a browser: reads your lockfile in the browser, never uploading it. - Whether it touches your code, with file and line: the Claude Code plugin, - As JSON: , or `POST https://api.agentprime.io/v1/match` with your packages () --- The web page: .
