CVE-2026-125753
Published:November 10, 2026
Updated:November 13, 2026
ABP Framework 2.9.0 before 10.6.2 and 10.7.0 pre-releases before 10.7.0 contain a path traversal vulnerability in DefaultBlobFilePathCalculator that allows unauthenticated attackers to access files outside the blob container. Attackers can send %5C-encoded backslashes through the Blogging api/blogging/files/{name} endpoint on Windows hosts to read files like appsettings.json containing signing keys and connection strings.
