## Summary

Authenticated attackers with custom-level access or higher can remotely delete arbitrary files on servers running the Photo Gallery, Sliders, Proofing and Themes – NextGEN Gallery plugin for WordPress, through insufficient file path validation in its handle_job function. Deleting critical files such as wp-config.php can lead to remote code execution, and the required capability is granted to Administrators by default but can be delegated to lower-privileged roles.

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

## Affected

- smub Photo Gallery, Sliders, Proofing and Themes – NextGEN Gallery: through 4.5.5

## Description

The Photo Gallery, Sliders, Proofing and Themes – NextGEN Gallery plugin for WordPress is vulnerable to arbitrary file deletion due to insufficient file path validation in the handle_job function in all versions up to, and including, 4.5.5 This makes it possible for authenticated attackers, with custom-level access and above, to delete arbitrary files on the server, which can easily lead to remote code execution when the right file is deleted (such as wp-config.php). The 'NextGEN Manage gallery' capability required to reach the vulnerable endpoint is granted to Administrators by default but can be delegated to lower-privileged roles via the plugin's Roles screen.

## Check your systems with an agent

```text
Check whether my systems are affected by CVE-2026-118191 (Photo Gallery, Sliders, Proofing and Themes <= 4.5.5 - Authenticated (Custom+) Arbitrary File Deletion via 'task_list' and 'app_config'…), 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-2026-118191 (entry last updated 2026-11-13):
Affected:
- smub Photo Gallery, Sliders, Proofing and Themes – NextGEN Gallery: through 4.5.5
Fixed versions: none listed yet.
Setup: unknown whether the bug needs a non-default feature or setting. Check the advisory.
CISA KEV: CVE-2026-118191 is not listed as of cve.now's last read.
This KEV status is for CVE-2026-118191 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:
