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-2026-45087 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-2026-45087/ (Markdown: https://insights.sbomify.com/CVE-2026-45087/index.md)","id":"CVE-2026-45087","markdown":"https://insights.sbomify.com/CVE-2026-45087/index.md","name":"CVE-2026-45087","record":{"aliases":["GHSA-v25v-m36w-jp4h","GO-2026-5649"],"analysis":{"component_type":"developer_tool","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":true,"product_category":"XSS scanner utility","requires_auth":"none","summary":"Unauthenticated attackers can execute arbitrary shell commands on the host by sending malicious JSON to the Dalfox server API.","user_interaction":"not_required","vuln_class":"command_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[],"cvss":{"score":10,"severity":"critical","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-78","name":"Improper Neutralization of Special Elements used in an OS Command"},{"id":"CWE-306","name":"Missing Authentication for Critical Functionality"},{"id":"CWE-15","name":"External Control of System or Configuration Setting"}],"description":"Dalfox is a powerful open-source XSS scanner and utility focused on automation. Prior to 2.13.0, when dalfox is started in REST API server mode (dalfox server), the server binds to 0.0.0.0:6664 by default and requires no API key unless the operator explicitly passes --api-key. Because model.Options — including FoundAction and FoundActionShell — is deserialized directly from attacker-supplied JSON in POST /scan, and because dalfox.Initialize explicitly propagates those two fields into the final scan options without stripping them, any unauthenticated caller who can reach the server port can supply an arbitrary shell command that the dalfox process will execute on the host whenever a scan finding is triggered. This vulnerability is fixed in 2.13.0.","ecosystems":["Go"],"exploits":{"exploitdb":0,"first_seen":"2026-05-07","github_poc":0,"max_poc_stars":null,"metasploit":1,"nuclei":0,"refs":[{"date":"2026-05-07","kind":"metasploit","ref":"exploit/linux/http/dalfox_server_rce_cve_2026_45087","stars":null,"title":"Dalfox Found-Action Deserialization RCE"}],"tier":"weaponised"},"has_fix":true,"headline":"Dalfox: Unauthenticated Remote Code Execution via `found-action` in Dalfox Server Mode","id":"CVE-2026-45087","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Go","product":null,"products":[],"type":"command_injection","year":"2026"},"n_packages":4,"n_references":2,"next":{"headline":"Dalfox Server Mode has an Unauthenticated Arbitrary File Read with Out-of-Band Exfiltration via `custom-payload-file`","id":"CVE-2026-45088"},"packages":[{"ecosystem":"Go","fixed":[],"introduced":["0"],"last_affected":[],"package":"github.com/hahwul/dalfox","purl":"pkg:golang/github.com/hahwul/dalfox","source":"GO-2026-5649"},{"ecosystem":"Go","fixed":["2.13.0"],"introduced":["0"],"last_affected":[],"package":"github.com/hahwul/dalfox/v2","purl":null,"source":"GHSA-v25v-m36w-jp4h"},{"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-v25v-m36w-jp4h"},{"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-2026-5649"}],"prev":{"headline":"Decidim: Forms admin question editor lacks authorization","id":"CVE-2026-45086"},"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)"},{"class":"attribution","licence":"BSD-3-Clause","name":"Metasploit"}],"ssvc":{"automatable":"yes","exploitation":"poc","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-05-28","vendors":["hahwul"]},"summary":"Unauthenticated attackers can execute arbitrary shell commands on the host by sending malicious JSON to the Dalfox server API.","url":"https://insights.sbomify.com/CVE-2026-45087/"}
