Summary
Apache Roller exposes sensitive data to other users when a weblog administrator, who must be logged in with low privileges, reaches it remotely through a custom weblog template. The template can read the stored password hash of the weblog's creator or of any author whose entry appears on the page.

Read the original description
Exposure of Sensitive Information to an Unauthorized Actor in Apache Roller 4.0 through 6.1.6 allows a weblog administrator to read another user's stored password hash by authoring a custom weblog template that reaches the wrapped persistent object behind the template's weblog or entry data, rather than the reduced set of fields the wrapper is meant to expose. Roller treats weblog administrators as untrusted and exposes weblog and entry data to templates only through wrapper classes, but a public accessor on those wrapper classes returned the underlying persistent object directly, including the stored password hash of the weblog's creator and of any author whose entry renders on the page. No non-default configuration is required; this affects any weblog whose administrator can author templates. Users are recommended to upgrade to Apache Roller 6.1.7 or later, which removes template access to the underlying wrapped objects.

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-2026-105152 (Apache Roller: Weblog template access to wrapped objects exposes another user's password hash), 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-2026-105152 (entry last updated 2026-11-11):
Affected:
- Apache Software Foundation Apache Roller: from 4.0, through 6.1.6
Fixed versions: none listed yet.
Setup: unknown whether the bug needs a non-default feature or setting. Check the advisory.
CISA KEV: CVE-2026-105152 is not listed as of cve.now's last read.
This KEV status is for CVE-2026-105152 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://lists.apache.org/thread/v1zondkgmfoh3y83l0l191qthmstcm39
- https://github.com/apache/roller/pull/199
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.
