Advisory record · `GHSA-cffv-grgg-g429` - **Identifiers:** `GHSA-cffv-grgg-g429` · `CVE-2026-14535` · `PYSEC-2026-2150` - **State:** Confirmed - **Severity:** CVSS 8.8 High - **Critical:** No - **Weakness (CWE):** [CWE-693](https://cwe.mitre.org/data/definitions/693.html) - **Tags:** [CWE-693](https://agentprime.io/advisories/tag/cwe-693.md) - **Published:** 4 Jul 2026 - **Updated:** 13 Jul 2026 - **Reviewed by a person:** No Published by the GitHub Advisory Database at 4 Jul 2026, 14:16 UTC. agentprime has not analysed this yet, so whether it affects any app is not known. ## Affected packages - `fickling` (PyPI): affected `<0.1.12`; fixed in `0.1.12` ## Machine-written summary Summary written by Claude Haiku from the source advisory. Not reviewed by a person. > Fickling versions up to and including 0.1.11 are vulnerable. The UnsafeImportsML analysis pass records every import it inspects in a shared set, which causes the MLAllowlist pass to skip its allowlist check entirely. An attacker who can supply a pickle file to a system that uses fickling's check_safety() or fickling.load() can get a malicious payload past the safety check using any standard library module not on the denylist, which may then execute when deserialized. Upgrade to fickling 0.1.12 or later. Written 6 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 - 8.8 High, CVSS 3.1: `CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H`, from CNA (BombadilSystems) - **CISA KEV:** Not listed. - **EPSS:** 0.0056, the 47th percentile, on 9 Nov 2026: FIRST’s estimate of the chance of exploitation in the next 30 days. ## Timeline - 31 Oct 2026, 15:04 UTC: First seen by agentprime - 31 Oct 2026, 15:04 UTC: [Confirmed by OSV](https://osv.dev/vulnerability/PYSEC-2026-2150) ## Sources - [GitHub Advisory Database: GHSA-cffv-grgg-g429](https://github.com/advisories/GHSA-cffv-grgg-g429) - [OSV: GHSA-cffv-grgg-g429](https://osv.dev/vulnerability/GHSA-cffv-grgg-g429) - - - 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: .
