CVE-2026-41889 is a low-severity SQL injection vulnerability in jackc pgx, published on 8 May 2026. Any signed-in user can exploit it over the network, with no action from the victim. ### Official description pgx is a PostgreSQL driver and toolkit for Go. Prior to version 5.9.2, SQL injection can occur when the non-default simple protocol is used, a dollar quoted string literal is used in the SQL query, that string literal contains text that would be would be interpreted as a placeholder outside of a string literal, and the value of that placeholder is controllable by the attacker. This issue has been patched in version 5.9.2.

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.
