CVE-2026-33658 [LOW] CWE-770 CVE-2026-33658: Active Storage allows users to attach cloud and local files in Rails applications. Prior to versions Active Storage allows users to attach cloud and local files in Rails applications. Prior to versions 8.1.2.1, 8.0.4.1, and 7.2.3.1 Active Storage's proxy controller does not limit the number of byte ranges in an HTTP Range header. A request with thousands of small ranges causes disproportionate CPU usage compared to a normal request for the same file,

CVE-2026-33195 [HIGH] CWE-22 CVE-2026-33195: Active Storage allows users to attach cloud and local files in Rails applications. Prior to versions Active Storage allows users to attach cloud and local files in Rails applications. Prior to versions 8.1.2.1, 8.0.4.1, and 7.2.3.1, Active Storage's `DiskService#path_for` does not validate that the resolved filesystem path remains within the storage root directory. If a blob key containing path traversal sequences (e.g. `../`) is used, it could allow

CVE-2026-33174 [MEDIUM] CWE-789 CVE-2026-33174: Active Storage allows users to attach cloud and local files in Rails applications. Prior to versions Active Storage allows users to attach cloud and local files in Rails applications. Prior to versions 8.1.2.1, 8.0.4.1, and 7.2.3.1, when serving files through Active Storage's proxy delivery mode, the proxy controller loads the entire requested byte range into memory before sending it. A request with a large or unbounded Range header (e.g. `bytes=0-

CVE-2026-33202 [MEDIUM] CWE-74 CVE-2026-33202: Active Storage allows users to attach cloud and local files in Rails applications. Prior to versions Active Storage allows users to attach cloud and local files in Rails applications. Prior to versions 8.1.2.1, 8.0.4.1, and 7.2.3.1, Active Storage's `DiskService#delete_prefixed` passes blob keys directly to `Dir.glob` without escaping glob metacharacters. If a blob key contains attacker-controlled input or custom-generated keys with glob metacharact

CVE-2026-33173 [MEDIUM] CWE-925 CVE-2026-33173: Active Storage allows users to attach cloud and local files in Rails applications. Prior to versions Active Storage allows users to attach cloud and local files in Rails applications. Prior to versions 8.1.2.1, 8.0.4.1, and 7.2.3.1, `DirectUploadsController` accepts arbitrary metadata from the client and persists it on the blob. Because internal flags like `identified` and `analyzed` are stored in the same metadata hash, a direct-upload client can
