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-2026-34570 exists.\n\nAffected packages and fixed versions:\n- ci4-cms-erp/ci4ms (Packagist): affected all versions; fixed in 0.31.0.0\n- ci4-cms-erp/ci4ms (Packagist): affected all versions; fixed in 0.31.0.0\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-2026-34570/ (Markdown: https://insights.sbomify.com/CVE-2026-34570/index.md)","id":"CVE-2026-34570","markdown":"https://insights.sbomify.com/CVE-2026-34570/index.md","name":"CVE-2026-34570","record":{"aliases":["GHSA-4vxv-4xq4-p84h"],"analysis":{"component_type":"web_application","fix_type":"patch","impacts":["privilege_escalation","security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"CodeIgniter CMS skeleton","requires_auth":"low_privilege","summary":"Deleted user accounts retain active session access indefinitely due to improper session invalidation, allowing unauthorized persistent access.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"ci4ms","vendor":"ci4-cms-erp"}],"cvss":{"score":8.8,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-613","name":"DEPRECATED: Insufficient Session Expiration"},{"id":"CWE-284","name":"Improper Access Control"},{"id":"CWE-1254","name":"Incorrect Comparison Logic Granularity"}],"description":"CI4MS is a CodeIgniter 4-based CMS skeleton that delivers a production-ready, modular architecture with RBAC authorization and theme support. Prior to version 0.31.0.0, the application fails to immediately revoke active user sessions when an account is deleted. Due to a logic flaw in the backend design, account state changes are enforced only during authentication (login), not for already-established sessions. The system implicitly assumes that authenticated users remain trusted for the lifetime of their session. There is no session expiration or account expiration mechanism in place, causing deleted accounts to retain indefinite access until the user manually logs out. This behavior breaks the intended access control policy and results in persistent unauthorized access. This issue has been patched in version 0.31.0.0.","ecosystems":["Packagist"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"weaponised"},"has_fix":true,"headline":"CI4MS: Account Deletion Module Grants Full Persistent Unauthorized Access for All‑Roles via Improper Session Invalidation (Logic Flaw)","id":"CVE-2026-34570","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Packagist","product":null,"products":[],"type":"missing_authorization","year":"2026"},"n_packages":2,"n_references":2,"next":{"headline":"CI4MS: Stored Cross‑Site Scripting (Stored XSS) in Backend User Management Allows Session Hijacking and Full Administrative Account Compromise","id":"CVE-2026-34571"},"packages":[{"ecosystem":"Packagist","fixed":["0.31.0.0"],"introduced":["0"],"last_affected":[],"package":"ci4-cms-erp/ci4ms","purl":null,"source":"GHSA-4vxv-4xq4-p84h"},{"ecosystem":"Packagist","fixed":["0.31.0.0"],"introduced":["0"],"last_affected":[],"package":"ci4-cms-erp/ci4ms","purl":"pkg:composer/ci4-cms-erp/ci4ms","source":"GHSA-4vxv-4xq4-p84h"}],"prev":{"headline":"CI4MS: Blogs Categories Full Account Takeover for All-Roles \u0026 Privilege-Escalation via Stored DOM XSS","id":"CVE-2026-34569"},"products":["ci4ms"],"published":"2026-04-01","related":[{"cvss_score":10,"headline":"CI4MS: Blogs Categories Full Account Takeover for All-Roles \u0026 Privilege-Escalation via Stored DOM XSS","id":"CVE-2026-34569","kev_date_added":null,"published":"2026-04-01"},{"cvss_score":10,"headline":"CI4MS: Stored Cross‑Site Scripting (Stored XSS) in Backend User Management Allows Session Hijacking and Full Administrative Account Compromise","id":"CVE-2026-34571","kev_date_added":null,"published":"2026-04-01"},{"cvss_score":10,"headline":"CI4MS Vulnerable to Remote Code Execution (RCE) via Arbitrary File Creation and Save in File Editor","id":"CVE-2026-25510","kev_date_added":null,"published":"2026-02-03"},{"cvss_score":9.4,"headline":"CI4MS: Profile \u0026 User Management Full Account Takeover for All-Roles \u0026 Privilege-Escalation via Stored DOM XSS","id":"CVE-2026-34989","kev_date_added":null,"published":"2026-04-06"},{"cvss_score":9.1,"headline":"CI4MS: Blogs Tags Full Account Takeover for All-Roles \u0026 Privilege-Escalation via Stored DOM XSS","id":"CVE-2026-34559","kev_date_added":null,"published":"2026-04-01"},{"cvss_score":9.1,"headline":"CI4MS: Logs Full Account Takeover for All-Roles \u0026 Privilege-Escalation via Stored DOM XSS","id":"CVE-2026-34560","kev_date_added":null,"published":"2026-04-01"},{"cvss_score":9.1,"headline":"CI4MS: Backup Management Full Account Takeover for All-Roles \u0026 Privilege-Escalation via Stored DOM Blind XSS","id":"CVE-2026-34563","kev_date_added":null,"published":"2026-04-01"}],"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":"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":"yes","exploitation":"poc","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-04-06","vendors":["ci4-cms-erp"]},"summary":"Deleted user accounts retain active session access indefinitely due to improper session invalidation, allowing unauthorized persistent access.","url":"https://insights.sbomify.com/CVE-2026-34570/"}
