## What is CVE-2026-13766?

CVE-2026-13766 is a critical SQL injection vulnerability in EXODIST DBIx::QuickORM, published on 30 Jun 2026. An attacker can exploit it over the internet without logging in, with no action from the victim.

### Official description

DBIx::QuickORM versions before 0.000026 for Perl allow SQL injection via unquoted SQL identifiers.

The default SQL builder, a SQL::Abstract subclass, sets bindtype in its constructor but never quote_char, so SQL::Abstract emits identifiers verbatim. Caller-supplied identifiers (order_by, where-clause column keys, field and returning lists, upsert columns, and join aliases) reach the SQL string raw, while values are placeholder-bound and unaffected.

A caller that forwards untrusted input to an affected identifier position, such as a user-controlled order_by value, enables SQL injection: the row order can be made to depend on a sub-select over columns the query never selected, and the where and update identifier positions permit further data disclosure and tampering.

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

Check this codebase for CVE-2026-13766 and fix it if it is affected.

What it is: CVE-2026-13766 is a critical SQL injection vulnerability in EXODIST DBIx::QuickORM, published on 30 Jun 2026. An attacker can exploit it over the internet without logging in, with no action from the victim.
Exploitation: There is no known exploitation of CVE-2026-13766 in the wild and no public exploit code.

Affected product: EXODIST DBIx::QuickORM. 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.
