CVE-2023-26268 — Apache Couchdb security vulnerability

Medium CVSS 5.3

Design documents with matching document IDs, from databases on the same cluster, may share a mutable Javascript environment when using these design document functions: * validate_doc_update * list * filter * filter views (using view functions as filters) * rewrite * update This doesn't affect map/reduce or search (Dreyfus) index functions. Users are recommended to upgrade to a version that is no longer affected by this issue (Apache CouchDB 3.3.2 or 3.2.3). Workaround: Avoid using design documents from untrusted sources which may attempt to cache or store data in the Javascript environment.

Matched remediation archetype

Information disclosure and sensitive data exposure

This catalog composition supplies bounded fallback guidance. Explicitly reviewed curated workflows load with the complete record below.

Check exposure

  • Trace sensitive data through responses, errors, logs, metrics, traces, caches, exports, files, backups, and client bundles.
  • Identify affected subjects, tenants, retention windows, access controls, and downstream copies without opening unnecessary sensitive records.
  • Review metadata, timing, status, length, and existence signals as well as direct content disclosure.

Remediate safely

  • Minimize collection and output, apply field-level authorization and redaction at a centralized boundary, and return generic external errors.
  • Remove secrets and sensitive data from logs, artifacts, URLs, caches, and client-side bundles; rotate credentials that may have been exposed.
  • Update the affected component and add synthetic-data tests for response, error, observability, and export paths.
