## What is CVE-2026-63460?

CVE-2026-63460 is a high-severity denial of service vulnerability in vendurehq vendure, published on 17 Sep 2026. An attacker can exploit it over the internet without logging in, with no action from the victim.

### Official description

Vendure is an open-source headless commerce platform. Prior to 3.6.5, the public Shop GraphQL API allows an unauthenticated caller to supply a catastrophically backtracking pattern through StringOperators.regex. packages/core/src/service/helpers/list-query-builder/parse-filter-params.ts passes the raw pattern to the REGEXP implementation registered by packages/core/src/service/helpers/list-query-builder/list-query-builder.ts, and better-sqlite3 and sqljs evaluate it synchronously in the Node.js event loop. ShopProductsResolver.products is publicly reachable, so one nested-quantifier pattern can block request processing and make the storefront and admin API unavailable, while repeated requests can sustain denial of service. PostgreSQL and MySQL or MariaDB deployments do not execute this regular expression in the Node.js event loop. This issue is fixed in version 3.6.5.

Weakness: CWE-1333 (Inefficient Regular Expression Complexity)

What it is: CVE-2026-63460 is a high-severity denial of service vulnerability in vendurehq vendure, published on 17 Sep 2026. An attacker can exploit it over the internet without logging in, with no action from the victim.
Exploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-63460 exists.

Affected packages and fixed versions:
- @vendure/core (npm): affected all versions; fixed in 3.6.5
- @vendure/core (npm): affected all versions; fixed in 3.6.5

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.
