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-2026-33680 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; fixed in 2.2.2\n- code.vikunja.io/api (Go): affected all versions; fixed in 2.2.2\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-2026-33680/ (Markdown: https://insights.sbomify.com/CVE-2026-33680/index.md)","id":"CVE-2026-33680","markdown":"https://insights.sbomify.com/CVE-2026-33680/index.md","name":"CVE-2026-33680","record":{"aliases":["GHSA-8hp8-9fhr-pfm9","GO-2026-4848"],"analysis":{"component_type":"web_application","fix_type":"patch","impacts":["privilege_escalation","account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"Vikunja task manager","requires_auth":"none","summary":"Attackers with read-only link shares can retrieve admin hashes to escalate privileges to full admin access in Vikunja.","user_interaction":"not_required","vuln_class":"privilege_escalation"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"vikunja","vendor":"vikunja"}],"cvss":{"score":7.5,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-285","name":"Improper Authorization"}],"description":"Vikunja is an open-source self-hosted task management platform. Prior to version 2.2.2, the `LinkSharing.ReadAll()` method allows link share authenticated users to list all link shares for a project, including their secret hashes. While `LinkSharing.CanRead()` correctly blocks link share users from reading individual shares via `ReadOne`, the `ReadAllWeb` handler bypasses this check by never calling `CanRead()`. An attacker with a read-only link share can retrieve hashes for write or admin link shares on the same project and authenticate with them, escalating to full admin access. Version 2.2.2 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 Vulnerable to Link Share Hash Disclosure via ReadAll Endpoint Enables Permission Escalation","id":"CVE-2026-33680","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Go","product":null,"products":[],"type":"privilege_escalation","year":"2026"},"n_packages":3,"n_references":3,"next":{"headline":"AVideo has Path Traversal in pluginRunDatabaseScript.json.php Enables Arbitrary SQL File Execution via Unsanitized Plugin Name","id":"CVE-2026-33681"},"packages":[{"ecosystem":"Go","fixed":[],"introduced":["0"],"last_affected":[],"package":"code.vikunja.io/api","purl":"pkg:golang/code.vikunja.io/api","source":"GO-2026-4848"},{"ecosystem":"Go","fixed":["2.2.2"],"introduced":["0"],"last_affected":[],"package":"code.vikunja.io/api","purl":null,"source":"GHSA-8hp8-9fhr-pfm9"},{"ecosystem":"Go","fixed":["2.2.2"],"introduced":["0"],"last_affected":[],"package":"code.vikunja.io/api","purl":"pkg:golang/code.vikunja.io/api","source":"GHSA-8hp8-9fhr-pfm9"}],"prev":{"headline":"Vikunja has SSRF via OpenID Connect Avatar Download that Bypasses Webhook SSRF Protections","id":"CVE-2026-33679"},"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’s Improper Access Control Enables Bypass of Administrator-Imposed Account Disablement","id":"CVE-2026-33316","kev_date_added":null,"published":"2026-03-24"},{"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"}],"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":"yes","exploitation":"poc","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-03-26","vendors":["go-vikunja"]},"summary":"Attackers with read-only link shares can retrieve admin hashes to escalate privileges to full admin access in Vikunja.","url":"https://insights.sbomify.com/CVE-2026-33680/"}
