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-2026-33316 exists.\n\nAffected packages and fixed versions:\n- code.vikunja.io/api (Go): affected all versions; no fix listed\n- code.vikunja.io/api (Go): affected all versions up to 2.1.0; no fix listed\n- code.vikunja.io/api (Go): affected all versions up to 2.1.0; 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-2026-33316/ (Markdown: https://insights.sbomify.com/CVE-2026-33316/index.md)","id":"CVE-2026-33316","markdown":"https://insights.sbomify.com/CVE-2026-33316/index.md","name":"CVE-2026-33316","record":{"aliases":["GHSA-vq4q-79hh-q767","GO-2026-4798"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["account_takeover","security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Vikunja task manager","requires_auth":"low_privilege","summary":"Disabled users can bypass administrator-imposed account disablement by resetting their password, regaining access to the Vikunja task management platform.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"vikunja","vendor":"vikunja"}],"cvss":{"score":8.1,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:N","version":"3.1"},"cwes":[{"id":"CWE-863","name":"Incorrect Authorization"},{"id":"CWE-862","name":"Missing Authorization"},{"id":"CWE-284","name":"Improper Access Control"}],"description":"Vikunja is an open-source self-hosted task management platform. Prior to version 2.2.0, a flaw in Vikunja’s password reset logic allows disabled users to regain access to their accounts. The `ResetPassword()` function sets the user’s status to `StatusActive` after a successful password reset without verifying whether the account was previously disabled. By requesting a reset token through `/api/v1/user/password/token` and completing the reset via `/api/v1/user/password/reset`, a disabled user can reactivate their account and bypass administrator-imposed account disablement. Version 2.2.0 patches the issue.","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":"Vikunja’s Improper Access Control Enables Bypass of Administrator-Imposed Account Disablement","id":"CVE-2026-33316","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Go","product":null,"products":[],"type":"auth_bypass","year":"2026"},"n_packages":3,"n_references":4,"next":{"headline":"OP-TEE: PKCS#11 TA out-of-bounds read and memory disclosure","id":"CVE-2026-33317"},"packages":[{"ecosystem":"Go","fixed":[],"introduced":["0"],"last_affected":[],"package":"code.vikunja.io/api","purl":"pkg:golang/code.vikunja.io/api","source":"GO-2026-4798"},{"ecosystem":"Go","fixed":[],"introduced":["0"],"last_affected":["2.1.0"],"package":"code.vikunja.io/api","purl":null,"source":"GHSA-vq4q-79hh-q767"},{"ecosystem":"Go","fixed":[],"introduced":["0"],"last_affected":["2.1.0"],"package":"code.vikunja.io/api","purl":"pkg:golang/code.vikunja.io/api","source":"GHSA-vq4q-79hh-q767"}],"prev":{"headline":"Vikunja has a 2FA Bypass via Caldav Basic Auth","id":"CVE-2026-33315"},"products":["vikunja"],"published":"2026-03-24","related":[{"cvss_score":9.8,"headline":"Vikunja Vulnerable to Account Takeover via Password Reset Token Reuse","id":"CVE-2026-28268","kev_date_added":null,"published":"2026-02-27"},{"cvss_score":9.1,"headline":"Vijkunja has Weak Password Policy Combined with Persistent Sessions After Password Change","id":"CVE-2026-27575","kev_date_added":null,"published":"2026-02-25"},{"cvss_score":8.6,"headline":"Vikunja Affected by XSS Via Task Preview","id":"CVE-2026-25935","kev_date_added":null,"published":"2026-02-11"},{"cvss_score":8.3,"headline":"Vikunja Affected by Privilege Escalation via Project Reparenting","id":"CVE-2026-35595","kev_date_added":null,"published":"2026-04-10"},{"cvss_score":8.1,"headline":"Vikunja has IDOR in Task Attachment ReadOne Allows Cross-Project File Access and Deletion","id":"CVE-2026-33678","kev_date_added":null,"published":"2026-03-24"},{"cvss_score":7.5,"headline":"Vikunja Vulnerable to Link Share Hash Disclosure via ReadAll Endpoint Enables Permission Escalation","id":"CVE-2026-33680","kev_date_added":null,"published":"2026-03-24"}],"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":"2026-03-26","vendors":["go-vikunja"]},"summary":"Disabled users can bypass administrator-imposed account disablement by resetting their password, regaining access to the Vikunja task management platform.","url":"https://insights.sbomify.com/CVE-2026-33316/"}
