Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-30861 exists.\n\nAffected packages and fixed versions:\n- github.com/Tencent/WeKnora (Go): affected from 0.2.5; fixed in 0.2.10\n- github.com/Tencent/WeKnora (Go): affected from 0.2.5; fixed in 0.2.10\n- github.com/Tencent/WeKnora (Go): affected from 0.2.6; fixed in 0.2.10\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-2026-30861/ (Markdown: https://insights.sbomify.com/CVE-2026-30861/index.md)","id":"CVE-2026-30861","markdown":"https://insights.sbomify.com/CVE-2026-30861/index.md","name":"CVE-2026-30861","record":{"aliases":["GHSA-r55h-3rwj-hcmg","GO-2026-4645"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"LLM document framework","requires_auth":"low_privilege","summary":"Unauthenticated attackers can execute arbitrary commands via command injection in MCP stdio configuration validation, leading to system compromise.","user_interaction":"not_required","vuln_class":"command_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"weknora","vendor":"tencent"}],"cvss":{"score":10,"severity":"critical","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/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"}],"description":"WeKnora is an LLM-powered framework designed for deep document understanding and semantic retrieval. From version 0.2.5 to before version 0.2.10, an unauthenticated remote code execution (RCE) vulnerability exists in the MCP stdio configuration validation. The application allows unrestricted user registration, meaning any attacker can create an account and exploit the command injection flaw. Despite implementing a whitelist for allowed commands (npx, uvx) and blacklists for dangerous arguments and environment variables, the validation can be bypassed using the -p flag with npx node. This allows any attacker to execute arbitrary commands with the application's privileges, leading to complete system compromise. This issue has been patched in version 0.2.10.","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":"WeKnora: Remote Code Execution (RCE) via Command Injection in MCP Stdio Configuration Validation","id":"CVE-2026-30861","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Go","product":null,"products":[],"type":"command_injection","year":"2026"},"n_packages":3,"n_references":1,"next":{"headline":"Critical Stored XSS \u0026 Privilege Escalation in Appsmith","id":"CVE-2026-30862"},"packages":[{"ecosystem":"Go","fixed":["0.2.10"],"introduced":["0.2.5"],"last_affected":[],"package":"github.com/Tencent/WeKnora","purl":null,"source":"GHSA-r55h-3rwj-hcmg"},{"ecosystem":"Go","fixed":["0.2.10"],"introduced":["0.2.5"],"last_affected":[],"package":"github.com/Tencent/WeKnora","purl":"pkg:golang/github.com/Tencent/WeKnora","source":"GHSA-r55h-3rwj-hcmg"},{"ecosystem":"Go","fixed":["0.2.10"],"introduced":["0.2.6"],"last_affected":[],"package":"github.com/Tencent/WeKnora","purl":"pkg:golang/github.com/Tencent/WeKnora","source":"GO-2026-4645"}],"prev":{"headline":"WeKnora: Remote Code Execution via SQL Injection Bypass in AI Database Query Tool","id":"CVE-2026-30860"},"products":["WeKnora"],"published":"2026-03-07","related":[{"cvss_score":10,"headline":"WeKnora: Remote Code Execution via SQL Injection Bypass in AI Database Query Tool","id":"CVE-2026-30860","kev_date_added":null,"published":"2026-03-07"},{"cvss_score":10,"headline":"WeKnora has Command Injection in MCP stdio test","id":"CVE-2026-22688","kev_date_added":null,"published":"2026-01-10"},{"cvss_score":8.8,"headline":"WeKnora: Broken Access Control in Tenant Management","id":"CVE-2026-30855","kev_date_added":null,"published":"2026-03-07"},{"cvss_score":6.9,"headline":"Tencent WeKnora test testEmbeddingModel server-side request forgery","id":"CVE-2025-11046","kev_date_added":null,"published":"2025-09-26"},{"cvss_score":6.5,"headline":"WeKnora: DNS Rebinding Vulnerability in web_fetch Tool Allows SSRF to Internal Resources","id":"CVE-2026-30858","kev_date_added":null,"published":"2026-03-07"},{"cvss_score":5.9,"headline":"WeKnora: SSRF via Redirection","id":"CVE-2026-30247","kev_date_added":null,"published":"2026-03-07"}],"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":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"poc","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-03-09","vendors":["Tencent"]},"summary":"Unauthenticated attackers can execute arbitrary commands via command injection in MCP stdio configuration validation, leading to system compromise.","url":"https://insights.sbomify.com/CVE-2026-30861/"}
