## What is CVE-2026-72607?

CVE-2026-72607 is a high-severity SQL injection vulnerability in Koha, published on 11 Aug 2026. Any signed-in user can exploit it over the network, with no action from the victim.

### Official description

A stored SQL injection vulnerability in Koha through 24.11.17, 25.05.12, 25.11.06, and 26.05.01 allows authenticated staff with the tools => items_batchmod permission to read arbitrary database contents by storing a SQL payload in the agefield value of an automatic item modification rule. The agefield value is stored verbatim to the system preference and later interpolated without parameterization into a SQL query in C4::Items::ToggleNewStatus (line 1228) when the scheduled cron job executes. The injection is SELECT-only under standard MariaDB/MySQL DBI single-statement execution; a time-based SLEEP payload is also achievable via the cron trigger. An attacker can read the entire Koha database including patron PII and staff bcrypt password hashes.

Weakness: CWE-89 (Improper Neutralization of Special Elements used in an SQL Command)

What it is: CVE-2026-72607 is a high-severity SQL injection vulnerability in Koha, published on 11 Aug 2026. Any signed-in user can exploit it over the network, with no action from the victim.
Exploitation: There is no known exploitation of CVE-2026-72607 in the wild and no public exploit code.

Affected product: Koha. 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.
5. If nothing in the project is affected, say so and change nothing.
