An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-45088 exists.\n\nAffected packages and fixed versions:\n- github.com/hahwul/dalfox/v2 (Go): affected all versions; fixed in 2.13.0\n- github.com/hahwul/dalfox/v2 (Go): affected all versions; fixed in 2.13.0\n- github.com/hahwul/dalfox/v2 (Go): affected all versions; fixed in 2.13.0\n- github.com/hahwul/dalfox (Go): affected all versions; no fix listed\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2026-45088/ (Markdown: https://insights.sbomify.com/CVE-2026-45088/index.md)","id":"CVE-2026-45088","markdown":"https://insights.sbomify.com/CVE-2026-45088/index.md","name":"CVE-2026-45088","record":{"aliases":["GHSA-35wr-x7v6-9fv2","GO-2026-5070"],"analysis":{"component_type":"developer_tool","fix_type":"upgrade","impacts":["data_read"],"network_reachable":"yes","non_default_config":true,"product_category":"XSS scanner tool","requires_auth":"none","summary":"Unauthenticated attackers can read arbitrary files on the host via path traversal in Dalfox server mode, exfiltrating data through scan traffic.","user_interaction":"not_required","vuln_class":"path_traversal"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[],"cvss":{"score":7.5,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-73","name":"External Control of File Name or Path"},{"id":"CWE-552","name":"Files or Directories Accessible to External Parties"},{"id":"CWE-306","name":"Missing Authentication for Critical Functionality"}],"description":"Dalfox is a powerful open-source XSS scanner and utility focused on automation. Prior to 2.13.0, when dalfox is run in REST API server mode, the custom-payload-file field in model.Options is JSON-tagged and deserialized directly from the attacker's request body, then propagated unchanged through dalfox.Initialize into the scan engine. The engine passes the value to voltFile.ReadLinesOrLiteral, which reads lines from any file path accessible to the dalfox process and embeds each line as an XSS payload in outbound HTTP requests directed at the attacker-controlled target URL. Because the server has no API key by default, an unauthenticated network attacker can exfiltrate the contents of arbitrary files on the dalfox host by reading them line-by-line through scan traffic. This vulnerability is fixed in 2.13.0.","ecosystems":["Go"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"weaponised"},"has_fix":true,"headline":"Dalfox Server Mode has an Unauthenticated Arbitrary File Read with Out-of-Band Exfiltration via `custom-payload-file`","id":"CVE-2026-45088","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Go","product":null,"products":[],"type":"path_traversal","year":"2026"},"n_packages":4,"n_references":2,"next":{"headline":"Dalfox: Unauthenticated Arbitrary File Create/Append via `output` Option in Dalfox Server Mode","id":"CVE-2026-45089"},"packages":[{"ecosystem":"Go","fixed":[],"introduced":["0"],"last_affected":[],"package":"github.com/hahwul/dalfox","purl":"pkg:golang/github.com/hahwul/dalfox","source":"GO-2026-5070"},{"ecosystem":"Go","fixed":["2.13.0"],"introduced":["0"],"last_affected":[],"package":"github.com/hahwul/dalfox/v2","purl":null,"source":"GHSA-35wr-x7v6-9fv2"},{"ecosystem":"Go","fixed":["2.13.0"],"introduced":["0"],"last_affected":[],"package":"github.com/hahwul/dalfox/v2","purl":"pkg:golang/github.com/hahwul/dalfox/v2","source":"GHSA-35wr-x7v6-9fv2"},{"ecosystem":"Go","fixed":["2.13.0"],"introduced":["0"],"last_affected":[],"package":"github.com/hahwul/dalfox/v2","purl":"pkg:golang/github.com/hahwul/dalfox/v2","source":"GO-2026-5070"}],"prev":{"headline":"Dalfox: Unauthenticated Remote Code Execution via `found-action` in Dalfox Server Mode","id":"CVE-2026-45087"},"products":["dalfox"],"published":"2026-05-27","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CC BY 4.0","name":"GitHub Advisory Database","prefix":"GHSA"},{"class":"attribution","licence":"CC BY 4.0","name":"Go Vulnerability Database","prefix":"GO"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"yes","exploitation":"poc","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-05-27","vendors":["hahwul"]},"summary":"Unauthenticated attackers can read arbitrary files on the host via path traversal in Dalfox server mode, exfiltrating data through scan traffic.","url":"https://insights.sbomify.com/CVE-2026-45088/"}
