Summary
The Crop Thumbnails WordPress plugin lets any logged-in user with upload permission, such as an Author by default, read the metadata of media attachments owned by other users and overwrite their generated thumbnails and stored metadata. The cause is missing ownership checks when attachments are read and re-cropped.
Written by anthropic/claude-haiku-5.5 from the sources below. Verify against them.
Read the original description
The Crop Thumbnails WordPress plugin before 1.10.0 does not perform object-level authorization when reading and re-cropping media attachments, allowing any authenticated user with the upload capability (the Author role by default) to read the metadata of, and overwrite the generated thumbnail files and stored metadata of, media attachments belonging to other users.

Check your systems with an agent
Paste this into a coding or ops agent. It checks your systems read-only and reports a table per asset.
Check whether my systems are affected by CVE-2026-110041 (Crop-Thumbnails < 1.10.0 - Author+ Arbitrary Attachment Read and Overwrite via crop REST Endpoints), 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-2026-110041 (entry last updated 2026-11-12):
Affected:
- Unknown Crop Thumbnails: fixed in 1.10.0
Fixed versions: 1.10.0.
Setup: unknown whether the bug needs a non-default feature or setting. Check the advisory.
CISA KEV: CVE-2026-110041 is not listed as of cve.now's last read.
This KEV status is for CVE-2026-110041 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:
- the references on https://cve.now/CVE-2026-110041
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.
