• CVE-2026-61432: 0.34% estimated exploitation activity in the next 30 days; percentile 27.84 (FIRST EPSS, 2026-11-03). This is a model estimate, not proof of exploitation or customer exposure.

FastContext path resolution permits absolute and traversal reads outside the workspace Summary PraisonAI's praisonaiagents.context.fast FastContext feature treats workspacepath as the root directory for code search, but its model-facing search tools and high-level readcontext() helper accept absolute paths and .. traversal paths without checking that the resolved path remains under that workspace. A lower-trust prompt or caller that can influence FastContext tool arguments can read, search, and enumerate files outside the intended project workspace; the resulting file content is then returned to the caller or injected into the model's tool-result context. Technical Details FastContextAgent documents workspacepath as the "Root directory for searches" and stores it as an absolute path: The same class exposes grepsearch, globsearch, readfile, and listdirectory as model function-call tools via gettools(). Those tools are intended to retrieve code context from the configured workspace.…

# Patch Next advisory brief: CVE-2026-61432

Advisory: PraisonAI: FastContext path resolution permits absolute and traversal reads outside the workspace
IDs: CVE-2026-61432, GHSA-4xxv-6wmf-xf45
Record: https://patchnext.com/advisories/cve-2026-61432 (revision 3, source checked 26 Oct 2026, 13:55 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: Medium (CVSS 5.7)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor fix available; fixed versions by package: praisonaiagents 1.6.78. A vendor fix does not mean a deployment is fixed.

## Affected components
- PyPI praisonaiagents: affected <= 1.6.77; fixed in 1.6.78

## Suggested inspection (read-only)
- `python -m pip show praisonaiagents`: prints the installed version. Run with the environment that serves production active.

## Supported action
Upgrade each affected component to a fixed version on its release line. For a transitive dependency, upgrade the parent package or add an override or constraint, then regenerate the lockfile. Redeploy every environment that ran an affected version.

## Required regression checks
- Run the test suite and a production build.
- Exercise the features that depend on praisonaiagents.
- Repeat the inspection and confirm that only fixed versions remain installed.

## Rollback considerations
- Keep the previous lockfile and deployment artifact. Rolling back reinstates the vulnerable version, so apply any documented mitigation while you fix forward.

## Unresolved questions
- Which deployments run an affected version?
- Exploitation status can change. Check again before lowering the priority.
- Mark the work resolved only after the fixed version is verified in production.
