{"apiVersion":"1.0","identifier":"CVE-2026-49989","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.","publishedAt":"2026-08-14T17:18:27","lastModifiedAt":"2026-08-14T18:17:35","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-49989","cvssScore":7.1,"cvssVector":"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/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/MVI:X/MVA:X/MSC:X/MSI:X/MSA:X/S:X/AU:X/R:X/V:X/RE:X/U:X","epssProbability":0.00269,"riskScore":0.73,"affectedProduct":"CrateDB","affectedVersions":"<6.2.8, <6.3.2","vulnerabilityType":"Library","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-49989","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-49989","en":"https://www.redsauce.net/en/cves/CVE-2026-49989","fr":"https://www.redsauce.net/fr/cves/CVE-2026-49989","pt":"https://www.redsauce.net/pt/cves/CVE-2026-49989","de":"https://www.redsauce.net/de/cves/CVE-2026-49989","sk":"https://www.redsauce.net/sk/cves/CVE-2026-49989","el":"https://www.redsauce.net/el/cves/CVE-2026-49989"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-49989"}}
