CVE-2026-59192 is not in CISA's Known Exploited Vulnerabilities (KEV) catalog. No public exploit code is tracked. It is rated CVSS 6.9 (medium) and affects twig-view; fixed in 1.3.3 and 2.1.2.

## Summary

The TwigView plugin for CakePHP has a deserialization flaw: its unserialize filter places no restrictions on which classes it accepts, so it can be used as a gadget for remote code execution. An attacker can reach it remotely over the network without logging in and without any action by a user.

Model-written summary (anthropic/claude-haiku-5.5). Verify details against the original sources.

## Affected

- cakephp twig-view: fixed in 1.3.3; from 2.0.0, fixed in 2.1.2

## Description

TwigView plugin for CakePHP provides wrappers for common View operations and extensions that expose CakePHP functions and jasny/twig-extensions helpers. Prior to versions 1.3.3 and 2.1.2, the unserialize filter has no restriction on which classes are allowed. This can used as a deserialization remote-code-execution gadget. This issue has been patched in versions 1.3.3 and 2.1.2.

## Check your systems with an agent

```text
Check whether my systems are affected by CVE-2026-59192 (TwigView: Deserialization of Untrusted Data), using the cve.now data below.

Rules: work read-only. Do not run exploit code, proof-of-concept scripts or scanners that send attack payloads, and do not change any configuration, package, image or deployment. Report findings only.

What cve.now has for CVE-2026-59192 (entry last updated 2026-11-11):
Affected:
- cakephp twig-view: fixed in 1.3.3; from 2.0.0, fixed in 2.1.2
Fixed versions: 1.3.3, 2.1.2.
Setup: unknown whether the bug needs a non-default feature or setting. Check the advisory.
CISA KEV: CVE-2026-59192 is not listed as of cve.now's last read.
This KEV status is for CVE-2026-59192 only. If you also check another CVE, look up its own KEV status; never assume it from this one.

How to check:
- Installed software: check what is actually running, not what a repo declares. Read the version from each host, container image and Kubernetes node (the binary's version output, the OS package database, image layers), and check whether the conditions above hold there. Distribution packages may carry a backported fix under an older version number; confirm against the distribution's own advisory.

Verify against the linked advisories before concluding, and cite the date you read each one:

- https://github.com/cakephp/twig-view/releases/tag/2.1.2
Do not conclude an asset is unaffected unless you checked it and the evidence covers both its version and the conditions above. If you could not check something, mark it unknown and say what is missing.

Report a table with one row per asset and these columns: Asset | Version or build | Status (affected, fixed, not applicable, unknown) | Compensating controls | Exposure (internet-facing, internal, none) | Evidence | Next action.
