# Logging operator has Fluentd configuration injection that allows remote code execution Advisory record · `GHSA-mjqf-28ph-426h` - **Identifiers:** `GHSA-mjqf-28ph-426h` · `CVE-2026-54680` · `GO-2026-6142` - **State:** Confirmed - **Severity:** CVSS 9.9 Critical - **Critical:** Yes: CVSS 9+ - **Weakness (CWE):** [CWE-74](https://cwe.mitre.org/data/definitions/74.html) · [CWE-77](https://cwe.mitre.org/data/definitions/77.html) - **Tags:** [Other injection](https://agentprime.io/advisories/tag/injection.md) · [Command injection](https://agentprime.io/advisories/tag/command-injection.md) - **Published:** 29 Jul 2026 - **Updated:** 10 Sept 2026 - **Reviewed by a person:** No Published by the GitHub Advisory Database at 29 Jul 2026, 17:01 UTC. agentprime has not analysed this yet, so whether it affects any app is not known. ## Critical Critical, because: - CVSS score 9.9: 9.0 or more. How we decide what’s critical: ## Affected packages - `github.com/kube-logging/logging-operator` (Go): affected `<0.0.0-20260608145523-cf437d7f1e05`; fixed in `0.0.0-20260608145523-cf437d7f1e05` ## Machine-written summary Summary written by Claude Haiku from the source advisory. Not reviewed by a person. > Logging operator (Go module github.com/kube-logging/logging-operator) is vulnerable before version 0.0.0-20260608145523-cf437d7f1e05, and that same version is listed as the fix. A user who can create Flow resources can inject Fluentd configuration through record_transformer.records because values are written into fluent.conf without escaping, which can add a block using the exec plugin and run arbitrary commands in the Fluentd aggregator. Upgrade to 0.0.0-20260608145523-cf437d7f1e05 or later; no workaround is listed. Written 1 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 - 9.9 Critical, CVSS 3.1: `CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H`, from CNA (GitHub_M) - **CISA KEV:** Not listed. - **EPSS:** 0.0078, the 56th percentile, on 14 Nov 2026: FIRST’s estimate of the chance of exploitation in the next 30 days. ## Timeline - 31 Oct 2026, 14:14 UTC: First seen by agentprime - 31 Oct 2026, 14:14 UTC: [Confirmed by OSV](https://osv.dev/vulnerability/GHSA-mjqf-28ph-426h) ## Sources - [GitHub Advisory Database: GHSA-mjqf-28ph-426h](https://github.com/advisories/GHSA-mjqf-28ph-426h) - [OSV: GHSA-mjqf-28ph-426h](https://osv.dev/vulnerability/GHSA-mjqf-28ph-426h) - - - - 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: .
