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-2026-68929 exists.\n\nAffected product: labring FastGPT. No package-level version data is available, so check the vendor advisory linked from the reference page.\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-2026-68929/ (Markdown: https://insights.sbomify.com/CVE-2026-68929/index.md)","id":"CVE-2026-68929","markdown":"https://insights.sbomify.com/CVE-2026-68929/index.md","name":"CVE-2026-68929","record":{"aliases":["GHSA-q4pr-3qpg-9q5v"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["account_takeover","denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"FastGPT LLM platform","requires_auth":"none","summary":"Unauthenticated attackers can hijack WeChat channels or cause denial of service by exploiting missing authorization checks on shareId-based endpoints.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[],"cvss":{"score":9.3,"severity":"critical","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-862","name":"Missing Authorization"},{"id":"CWE-306","name":"Missing Authentication for Critical Functionality"}],"description":"FastGPT is an open-source LLM platform for building AI applications on a knowledge base. In versions prior to 4.15.2, the WeChat (iLink) share-channel endpoints authorize requests using only the public shareId, with no authenticated identity or team-ownership check. As a result, an unauthenticated attacker who knows a victim team's shareId can take that team's WeChat bot offline or hijack the channel to their own bot: the logout endpoint is gated only by an existence check yet wipes the outLink's stored WeChat token, and the QR-code status endpoint performs no authorization at all and writes attacker-supplied bot credentials into the outLink identified by shareId. By generating a QR for a victim shareId, scanning it with their own WeChat, and calling the status endpoint, an attacker binds the victim team's app to the attacker's bot, exposing the app's private responses, displacing the legitimate binding, and consuming the victim's resources. The shareId is exposed in every shared chat URL, iframe, and embed, so it is not a secret. This issue is fixed in version 4.15.2.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":"2026-08-29","github_poc":1,"max_poc_stars":0,"metasploit":0,"nuclei":0,"refs":[{"date":"2026-08-29T08:56:47Z","kind":"github_poc","ref":"https://github.com/Hunt-Benito/your-bot-my-inbox-cve-2026-68929-fastgpt-unauthenticated-wechat-channel-hijack","stars":0,"title":null}],"tier":"weaponised"},"has_fix":false,"headline":"FastGPT: Unauthenticated WeChat channel hijack and denial of service via shareId-only authorization","id":"CVE-2026-68929","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"missing_authorization","year":"2026"},"n_packages":0,"n_references":2,"next":{"headline":"Russh: Channel-scoped server callbacks can be reached without an open channel","id":"CVE-2026-68930"},"packages":[],"prev":{"headline":"Command injection in Acode","id":"CVE-2026-68928"},"products":["FastGPT"],"published":"2026-08-27","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"},{"class":"open","licence":"CC0","name":"PoC-in-GitHub"}],"ssvc":{"automatable":"yes","exploitation":"poc","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-08-28","vendors":["labring"]},"summary":"Unauthenticated attackers can hijack WeChat channels or cause denial of service by exploiting missing authorization checks on shareId-based endpoints.","url":"https://insights.sbomify.com/CVE-2026-68929/"}
