## What is CVE-2026-68529?

CVE-2026-68529 is a low-severity missing authorization vulnerability in Concrete CMS, published on 15 Sep 2026. An attacker needs administrator access to exploit it, with no action from the victim.

### Official description

Concrete CMS 9.0.0 through 9.5.2 was missing an authorization check on the Express entries advanced-search dashboard action. The advanced_search() method in DashboardSelectableExpressEntryListTrait resolved an Express entity directly from a user-supplied entity ID and rendered that entity's entries without invoking canViewExpressEntries(), the per-entity permission check that the sibling results() action enforced. An authenticated dashboard user holding view_express_entries on a single Express entity could read the entries of any other entity, including secret attribute values, by requesting the advanced-search action with that entity's ID, disclosing form submissions and CRM-style records across the per-entity permission boundary that Express is designed to enforce. The Concrete CMS security team gave this vulnerability a CVSS v4.0 score of 2.1 with vector CVSS:4.0/AV:N/AC:L/AT:P/PR:H/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N. Thanks Winston Crooker for reporting.

Exploitation: There is no known exploitation of CVE-2026-68529 in the wild and no public exploit code.

Affected product: Concrete CMS. No package-level version data is available, so check the vendor advisory linked from the reference page.

Task:
1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.
2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.
3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.
4. Run the tests and summarise what changed and why.
