CVE-2022-3991: Photospace Gallery <= 2.3.5 - Authenticated (Subscriber+) Stored Cross-Site Scripting

The Photospace Gallery plugin for WordPress is vulnerable to Stored Cross-Site Scripting via its settings parameters saved via the update() function in versions up to, and including, 2.3.5 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with subscriber-level permissions and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

Security readout for executives and security teams

Plain-English summary

Photospace Gallery for WordPress can store unsafe script content in plugin settings on versions up to 2.3.5. A logged-in user with subscriber-level access or higher could make script run for visitors who open affected pages.

Executive priority

Treat as a moderate-priority web risk. It is not documented here as actively exploited or unauthenticated, but it can enable browser-side compromise and content manipulation on affected WordPress sites.

Technical view

CWE-79 stored XSS exists in Photospace Gallery settings handled by update(), caused by insufficient input sanitization and output escaping. The CVSS 3.1 vector is AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:N, with a 6.4 medium score.

Likely exposure

WordPress sites running Photospace Gallery up to and including 2.3.5 are the relevant exposure. Risk is higher where public registration, many subscribers, or shared editorial access exists.

Exploitation context

The source bundle does not show CISA KEV listing or active exploitation evidence. Exploitation requires an authenticated account with subscriber-level permissions or higher, then relies on stored script execution when an affected page is accessed.

Researcher notes

Evidence is limited to the CVE description, Wordfence references, and WordPress plugin source link. The bundle does not name a fixed version, so remediation should be confirmed against current vendor or WordPress plugin guidance.

Mitigation direction

  • Inventory WordPress sites for Photospace Gallery and version details.
  • Update Photospace Gallery if vendor guidance identifies a fixed release.
  • Disable or remove the plugin where it is not business-critical.
  • Limit subscriber registration and low-privileged accounts on affected sites.
  • Review Wordfence and WordPress plugin guidance for current remediation status.

Validation and detection

  • Confirm whether Photospace Gallery is installed on each WordPress site.
  • Flag versions up to and including 2.3.5 for remediation review.
  • Review subscriber and higher-privileged user lists for unnecessary accounts.
  • Inspect plugin settings and affected pages for unexpected script content.
  • Verify remediation in staging before returning affected sites to normal operation.
