{"schema":"threatline.record/2","record":{"id":"CVE-2026-113668","aliases":["GHSA-gqh3-7856-rjjg"],"summary":"ApostropheCMS: :_id/locales REST route omits the public-API authorization gate its sibling read routes enforce (unauthenticated doc-existence + locale metadata disclosure)","details":"## Summary\nThe REST route `GET /api/v1/<piece-type>/:_id/locales` (and the equivalent page route) does not apply the `publicApiCheckAsync` gate that ApostropheCMS's other read routes enforce. An unauthenticated caller can therefore query this route for any document `_id` and learn whether the document exists and which locales it is published in — a document-existence and locale-metadata disclosure that the read-API is otherwise supposed to gate.\n \n## Affected\n- Repository: `apostrophecms/apostrophe` (monorepo package `apostrophe`).\n- Confirmed at **4.32.2** (commit `d3ff8c9` == the shipped 4.32.2; unchanged at current HEAD). No fix at time of report.\n- Stack: Node.js / Express + MongoDB.\n- Endpoints: `GET /api/v1/<piece-type>/:_id/locales` and `GET /api/v1/@apostrophecms/page/:_id/locales`.\n\n## Technical detail\n- Unsafe: `modules/@apostrophecms/piece-type/index.js:397` registers the `:_id/locales` route with **no** `publicApiCheckAsync`. The page module has the same omission at `modules/@apostrophecms/page/index.js:925`.\n- Gated siblings: the read routes in the same module (e.g. `getAll` at `piece-type/index.js:256-263`) call `publicApiCheckAsync` (`:263`) to enforce the public-API access policy.\n- So the `locales` handler (which calls `getLocales()` for the document) runs for any caller regardless of the public-API gate the other read routes apply, returning the document's locale/publication metadata without authorization.\n\n## Impact\n\nAn unauthenticated caller can confirm the existence of a document by `_id` and enumerate its locales/publication state — information the read-API is meant to gate. Defensibly 4.3 (AC:H) given the opaque `_id` precondition (the caller needs a document id).\n \n## How it was verified (local only)\nReproduced against `apostrophe@4.32.2` (== commit `d3ff8c9`) locally with synthetic content:\n- Source review confirmed the `:_id/locales` route lacks `publicApiCheckAsync` while the sibling read routes have it.\n- An **unauthenticated** `GET /api/v1/<piece-type>/<_id>/locales` returned the document's locale metadata (existence + locales), while the gated read routes (e.g. `getAll`) correctly required the public-API policy.\n- Control: the same route with the `publicApiCheckAsync` gate added (matching the siblings) denies the unauthenticated request — isolating the missing gate as the cause.\nSynthetic content only; nothing hosted was touched.\n \n## Remediation\nAdd the `publicApiCheckAsync` (or equivalent) authorization gate to the `:_id/locales` route in both the piece-type and page modules, matching the sibling read routes, so the locale/existence metadata is only returned to callers permitted by the public-API policy.\n \n## Credit\nPlease credit **Santosh Kumar Puppala** (https://github.com/Santoshkumarpuppala).","categories":["Libraries & packages"],"product":"apostrophe","vendor":"apostrophecms","ecosystem":"npm","affected_ranges":[{"source":"GitHub Advisory Database","source_url":"https://github.com/advisories/GHSA-gqh3-7856-rjjg","source_modified_at":"2026-10-20T18:14:33Z","fetched_at":"2026-10-23T18:42:43.628194Z","package":{"ecosystem":"npm","name":"apostrophe"},"range":"< 4.33.0"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-113668","source_modified_at":"2026-10-20T19:04:47.799Z","fetched_at":"2026-10-23T18:45:31.882637Z","product":"apostrophe","vendor":"apostrophecms","versions":[{"status":"affected","version":"< 4.33.0"}],"defaultStatus":null},{"source":"OSV","source_url":"https://osv.dev/vulnerability/GHSA-gqh3-7856-rjjg","source_modified_at":"2026-10-20T18:30:03.574883961Z","fetched_at":"2026-10-23T18:52:38.922436Z","package":{"name":"apostrophe","ecosystem":"npm","purl":"pkg:npm/apostrophe"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"4.33.0"}]}],"versions":[]}],"fixed_versions":[{"source":"GitHub Advisory Database","source_url":"https://github.com/advisories/GHSA-gqh3-7856-rjjg","source_modified_at":"2026-10-20T18:14:33Z","fetched_at":"2026-10-23T18:42:43.628194Z","package":{"ecosystem":"npm","name":"apostrophe"},"version":"4.33.0"},{"source":"OSV","source_url":"https://osv.dev/vulnerability/GHSA-gqh3-7856-rjjg","source_modified_at":"2026-10-20T18:30:03.574883961Z","fetched_at":"2026-10-23T18:52:38.922436Z","package":{"name":"apostrophe","ecosystem":"npm","purl":"pkg:npm/apostrophe"},"version":"4.33.0"}],"cvss":5.3,"severity":"Medium","kev":{"listed":false},"epss":{"probability":0.00322,"percentile":0.24026,"score_date":"2026-10-23"},"published_at":"2026-10-20T17:32:07.486Z","modified_at":"2026-10-20T19:04:47.799Z","provenance":[{"source":"GitHub Advisory Database","url":"https://github.com/advisories/GHSA-gqh3-7856-rjjg","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-20T18:14:33Z"},{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-113668","fetched_at":"2026-10-23T18:45:31.882637Z","source_modified_at":"2026-10-20T19:04:47.799Z"},{"source":"OSV","url":"https://osv.dev/vulnerability/GHSA-gqh3-7856-rjjg","fetched_at":"2026-10-23T18:52:38.922436Z","source_modified_at":"2026-10-20T18:30:03.574883961Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-113668","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23"}],"sources":["GitHub Advisory Database","CVE List","OSV","EPSS"],"references":[{"source":"CVE List","url":"https://github.com/apostrophecms/apostrophe/security/advisories/GHSA-gqh3-7856-rjjg","tags":["x_refsource_CONFIRM"]},{"source":"CVE List","url":"https://github.com/apostrophecms/apostrophe/commit/9500b8b0e1d630d5e07fbb5fd2c25ed0943845ce","tags":["x_refsource_MISC"]},{"source":"CVE List","url":"https://github.com/apostrophecms/apostrophe/commit/f84fd41cbf6c22eb8d0008fc9c25df1f7130b350","tags":["x_refsource_MISC"]},{"source":"CVE List","url":"https://github.com/apostrophecms/apostrophe/releases/tag/apostrophe@4.33.0","tags":["x_refsource_MISC"]},{"url":"https://github.com/advisories/GHSA-gqh3-7856-rjjg","source":"GitHub Advisory Database"}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","ssvc":{"exploitation":"none","automatable":"yes","technical_impact":"partial","assessed_at":"2026-10-20T19:04:39.578019Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":"ecosystem","confidence":"heuristic","reviewed":false},"change_timestamp":"2026-10-20T19:04:47.799Z","content_hash":"9f881251c1be0df5772be6569a26ae20965673ae787cd6053458cedb5d5a1a2c"}}
