# Path Traversal in Action View Advisory record · `GHSA-86g5-2wh3-gc9j` - **Identifiers:** `GHSA-86g5-2wh3-gc9j` · `CVE-2019-5418` - **State:** Confirmed - **Severity:** CVSS 7.5 High - **Critical:** Yes: KEV, CVSS 7+ and EPSS - **Weakness (CWE):** [CWE-22](https://cwe.mitre.org/data/definitions/22.html) - **Tags:** [Path traversal](https://agentprime.io/advisories/tag/path-traversal.md) - **Published:** 13 Mar 2019 - **Updated:** 22 Oct 2025 - **Reviewed by a person:** No Published by the GitHub Advisory Database at 13 Mar 2019, 17:26 UTC. agentprime has not analysed this yet, so whether it affects any app is not known. ## Critical Critical, because: - In CISA’s KEV catalogue since 7 Jul 2025: it is known to be exploited. - CVSS score 7.5 (7.0 or more) and EPSS 0.99 (0.1 or more): a high score and a real chance of exploitation in the next 30 days. How we decide what’s critical: ## Affected packages - `actionview` (RubyGems): affected `>=5.2.0, <5.2.2.1 || >=4.0.0, <4.2.11.1 || >=5.1.0, <5.1.6.2 || >=5.0.0, <5.0.7.2`; fixed in `5.2.2.1`, `4.2.11.1`, `5.1.6.2`, `5.0.7.2` ## 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 - 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/E:H`, from GitHub Advisory Database - **CISA KEV:** Listed since 7 Jul 2025: known to be exploited. - **EPSS:** 0.99, the 99th percentile, on 10 Nov 2026: FIRST’s estimate of the chance of exploitation in the next 30 days. ## Timeline This record came from the full history of the GitHub Advisory Database, published 13 Mar 2019.

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: .
