# Opencast publishes global system account credentials Advisory record · `GHSA-hcxx-mp6g-6gr9` - **Identifiers:** `GHSA-hcxx-mp6g-6gr9` · `CVE-2018-16153` - **State:** Confirmed - **Severity:** CVSS 7.5 High - **Critical:** No - **Weakness (CWE):** [CWE-200](https://cwe.mitre.org/data/definitions/200.html) · [CWE-522](https://cwe.mitre.org/data/definitions/522.html) - **Tags:** [Information disclosure](https://agentprime.io/advisories/tag/info-disclosure.md) · [Hard-coded credentials](https://agentprime.io/advisories/tag/hard-coded-credentials.md) - **Published:** 14 Dec 2021 - **Updated:** 10 Sept 2026 - **Reviewed by a person:** No Published by the GitHub Advisory Database at 14 Dec 2021, 21:43 UTC. agentprime has not analysed this yet, so whether it affects any app is not known. ## Affected packages - `org.opencastproject:opencast-common` (Maven): affected `<10.6`; fixed in `10.6` ## Machine-written summary Summary written by Claude Haiku from the source advisory. Not reviewed by a person. > Opencast versions before 10.6 (org.opencastproject:opencast-common) send the global system user's credentials to any external service listed in a media package when accessing its files, whether or not that service belongs to the Opencast cluster. An attacker who can supply a media package with a malicious external file location could capture those credentials, though earlier mitigations already blocked cleartext authentication. Upgrade to Opencast 10.6, which only authenticates against servers in the Opencast cluster. No workaround is available.

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 - 7.5 High, CVSS 3.1: `CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N`, from GitHub Advisory Database - **CISA KEV:** Not listed. - **EPSS:** 0.0083, the 58th percentile, on 14 Nov 2026: FIRST’s estimate of the chance of exploitation in the next 30 days. ## Timeline - 31 Oct 2026, 14:18 UTC: First seen by agentprime - 31 Oct 2026, 14:18 UTC: [Confirmed by OSV](https://osv.dev/vulnerability/GHSA-hcxx-mp6g-6gr9) ## Sources - [GitHub Advisory Database: GHSA-hcxx-mp6g-6gr9](https://github.com/advisories/GHSA-hcxx-mp6g-6gr9) - [OSV: GHSA-hcxx-mp6g-6gr9](https://osv.dev/vulnerability/GHSA-hcxx-mp6g-6gr9) - - - - - - - - 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: .
