From 1.0.0-beta.10 until 1.0.0-beta.13 of the AI helper, an editor with image-generation capability can create a base64-generated image record without a stored provider URL and invoke image acceptance on a deployment using local relative storage with no trusted global base URL. The server resolves the fixed uploads path against a request-controlled Host-derived origin, enabling bounded server-side requests to an attacker-selected host, port, and HTTP origin, but not arbitrary-path retrieval or the stored-provider and absolute-storage configurations. This issue is fixed in AI helper 1.0.0-beta.13.","state":0,"publishedAt":"2026-10-20T17:43:53.227+00:00","modifiedAt":"2026-10-20T18:21:05.814+00:00","affected":[{"ecosystem":"Vendor product","name":"apostrophe","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"apostrophecms\",\n                    \"product\": \"apostrophe\",\n                    \"versions\": [\n                        {\n                            \"version\": \">= 4.25.0, < 4.33.0\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"},{"ecosystem":"Vendor product","name":"ai-helper","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"@apostrophecms\",\n                    \"product\": \"ai-helper\",\n                    \"versions\": [\n                        {\n                            \"version\": \">= 1.0.0-beta.10, < 1.0.0-beta.13\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N","score":4.3,"severity":"MEDIUM"}],"references":["https://github.com/apostrophecms/apostrophe/security/advisories/GHSA-527g-ff96-x6wj","https://github.com/apostrophecms/apostrophe/commit/9500b8b0e1d630d5e07fbb5fd2c25ed0943845ce","https://github.com/apostrophecms/apostrophe/commit/f84fd41cbf6c22eb8d0008fc9c25df1f7130b350","https://github.com/apostrophecms/apostrophe/releases/tag/@apostrophecms/ai-helper@1.0.0-beta.13"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-113671","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-113671","identifiers":["CVE-2026-113671"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
