CVE intelligence and bounded remediation
CVE-2022-0750 — Thriveweb Photoswipe Masonry Gallery security vulnerability
The Photoswipe Masonry Gallery WordPress plugin is vulnerable to Cross-Site Scripting due to insufficient escaping and sanitization of the thumbnail_width, thumbnail_height, max_image_width, and max_image_height parameters found in the ~/photoswipe-masonry.php file which allows authenticated attackers to inject arbitrary web scripts into galleries created by the plugin and on the PhotoSwipe Options page. This affects versions up to and including 1.2.14.

Matched remediation archetype
Cross-site scripting and unsafe browser output
This catalog composition supplies bounded fallback guidance. Explicitly reviewed curated workflows load with the complete record below.
Check exposure
- Trace reflected, stored, and DOM-derived untrusted values into HTML, attributes, URLs, styles, scripts, and client-side template sinks.
- Identify affected origins, authenticated user roles, sensitive browser capabilities, and where content is shared across tenants.
- Review framework escaping, rich-text sanitization, legacy templates, and client-side rendering paths.
Remediate safely
- Use context-aware framework output encoding and safe DOM APIs; keep untrusted data out of executable contexts.
- Sanitize intentionally supported markup with a maintained allowlist policy and validate URLs and attributes separately.
- Update affected rendering components and add tests for every output context using inert sentinel markup.
