• CVE-2026-54569: 1.16% estimated exploitation activity in the next 30 days; percentile 67.09 (FIRST EPSS, 2026-11-03). This is a model estimate, not proof of exploitation or customer exposure.

As published by the source; long descriptions are shortened.

Summary An unauthenticated remote code execution vulnerability in the SENAITE JSON API allows any network-reachable attacker to execute arbitrary Python on the Zope worker process via a two-request anonymous chain. The /@@API/update route is reachable to anonymous callers and runs eval() on attacker-controlled input before any permission check fires. This is a different code path from the eval() in the calculations module: no authenticated account of any kind is required. Details The vulnerability is the chain of two independent flaws. Either fix alone breaks the unauthenticated chain, but the eval sink remains exploitable by any authenticated user with write access to a RecordsField, so both fixes are needed. 1. Missing AccessJSONAPI gate on JSON API write routes (CWE-862). The route at src/bika/lims/jsonapi/update.py:45-165 does not enforce the senaite.core: Access JSON API permission upfront. Compare with the sibling create.py:179-182, which does: The check is present on create…

# Patch Next advisory brief: CVE-2026-54569

Advisory: senaite.core Vulnerable to Eval Injection and Missing Authorization
IDs: CVE-2026-54569, GHSA-jrw6-7x4q-w25j
Record: https://patchnext.com/advisories/cve-2026-54569 (revision 3, source checked 26 Oct 2026, 13:50 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: Critical (CVSS 9.8)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor response not established. A vendor fix does not mean a deployment is fixed.

## Affected components
- PyPI senaite-core: affected >= 2.0.0, <= 2.6.0

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

## Supported action
No complete vendor fix is recorded. Follow the primary source's mitigation guidance and check this record again before closing anything.

## Required regression checks
- Run the test suite and a production build.
- Exercise the features that depend on senaite-core.
- 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.
