{"cve":"CVE-2026-49989","nvd":{"published":"2026-08-14T17:18:27.290","modified":"2026-09-18T20:09:01.757","status":"Deferred","description":"CrateDB is a distributed SQL database. Prior to versions 6.2.8 and 6.3.2, any authenticated user can read or delete any blob whose SHA-1 digest they know, and can plant new blobs unconditionally, in any blob table, regardless of `GRANT`s. CrateDB has two ways to access blob storage: SQL (`SELECT ... FROM blob.<table>` and friends) and the blob HTTP API (`GET|PUT|DELETE /_blobs/{table}/{digest}`). The SQL path goes through `AccessControl`, which is what enforces privilege grants; that's why `SELECT digest FROM blob.secret_blobs` fails for a user who has no grants on the table. The HTTP path authenticates the request but never asks `AccessControl` whether the authenticated user is allowed to touch the table. So a user with no grants gets `MissingPrivilegeException` from SQL and `200 OK` plus the blob bytes from `GET /_blobs/secret_blobs/<digest>`. Deployments that don't use `BLOB TABLE` are unaffected. Authentication itself still works; the bug is strictly that being authenticated as anyone is treated as sufficient for any blob op. Versions 6.2.8 and 6.3.2 fix the issue.","cvss_v4":{"vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:N/VI:H/VA:N/SC:N/SI:N/SA:N","score":7.1},"cvss_v3":null,"cwes":["CWE-863"],"references":["https://github.com/crate/crate/security/advisories/GHSA-2xv8-gjwh-fv8p","https://github.com/crate/crate/security/advisories/GHSA-2xv8-gjwh-fv8p"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:48:17.459049833+00:00"},"epss":{"cve":"CVE-2026-49989","score":0.0047,"percentile":0.40635,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-2xv8-gjwh-fv8p","url":"https://osv.dev/vulnerability/GHSA-2xv8-gjwh-fv8p","summary":"CrateDB's Blob HTTP handler bypasses authorization","modified":"2026-07-01T20:11:28.416490Z","packages":[{"ecosystem":"Maven","name":"io.crate:crate","purl":"pkg:maven/io.crate/crate","ranges":["<6.2.8"],"fixed":["6.2.8"]},{"ecosystem":"Maven","name":"io.crate:crate","purl":"pkg:maven/io.crate/crate","ranges":[">=6.3.0 <6.3.2"],"fixed":["6.3.2"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
