An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2026-28681 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- irrd (PyPI): affected from 4.4.0; fixed in 4.4.5, 4.5.1\n- irrd (PyPI): affected from 4.4.0; fixed in 4.4.5\n- irrd (PyPI): affected from 4.4.0; fixed in 4.4.5\n- irrd (PyPI): affected from 4.5.0; fixed in 4.5.1\n- irrd (PyPI): affected from 4.5.0; fixed in 4.5.1\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-2026-28681/ (Markdown: https://insights.sbomify.com/CVE-2026-28681/index.md)","id":"CVE-2026-28681","markdown":"https://insights.sbomify.com/CVE-2026-28681/index.md","name":"CVE-2026-28681","record":{"aliases":["GHSA-22m3-c7vp-49fj","PYSEC-2026-2186"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["account_takeover","data_modify"],"network_reachable":"yes","non_default_config":false,"product_category":"IRR database server","requires_auth":"none","summary":"Attackers can poison password reset links via Host header injection to steal tokens and take over user accounts, allowing modification of routing registry objects.","user_interaction":"required","vuln_class":"open_redirect"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"internet_routing_registry_daemon","vendor":"internet_routing_registry_daemon_project"}],"cvss":{"score":8.1,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:N","version":"3.1"},"cwes":[{"id":"CWE-640","name":"Weak Password Recovery Mechanism for Forgotten Password"},{"id":"CWE-601","name":"URL Redirection to Untrusted Site"}],"description":"Internet Routing Registry daemon version 4 is an IRR database server, processing IRR objects in the RPSL format. From version 4.4.0 to before version 4.4.5 and from version 4.5.0 to before version 4.5.1, an attacker can manipulate the HTTP Host header on a password reset or account creation request. The confirmation link in the resulting email can then point to an attacker-controlled domain. Opening the link in the email is sufficient to pass the token to the attacker, who can then use it on the real IRRD instance to take over the account. A compromised account can then be used to modify RPSL objects maintained by the account's mntners and perform other account actions. If the user had two-factor authentication configured, which is required for users with override access, an attacker is not able to log in, even after successfully resetting the password. This issue has been patched in versions 4.4.5 and 4.5.1.","ecosystems":["PyPI"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"IRRd: web UI host header injection allows password reset poisoning via attacker-controlled email links","id":"CVE-2026-28681","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"PyPI","product":null,"products":[],"type":"open_redirect","year":"2026"},"n_packages":5,"n_references":5,"next":{"headline":"Gokapi: Data Leak in Upload Status Stream","id":"CVE-2026-28682"},"packages":[{"ecosystem":"PyPI","fixed":["4.4.5","4.5.1"],"introduced":["4.4.0","4.5.0"],"last_affected":[],"package":"irrd","purl":"pkg:pypi/irrd","source":"PYSEC-2026-2186"},{"ecosystem":"PyPI","fixed":["4.4.5"],"introduced":["4.4.0"],"last_affected":[],"package":"irrd","purl":null,"source":"GHSA-22m3-c7vp-49fj"},{"ecosystem":"PyPI","fixed":["4.4.5"],"introduced":["4.4.0"],"last_affected":[],"package":"irrd","purl":"pkg:pypi/irrd","source":"GHSA-22m3-c7vp-49fj"},{"ecosystem":"PyPI","fixed":["4.5.1"],"introduced":["4.5.0"],"last_affected":[],"package":"irrd","purl":null,"source":"GHSA-22m3-c7vp-49fj"},{"ecosystem":"PyPI","fixed":["4.5.1"],"introduced":["4.5.0"],"last_affected":[],"package":"irrd","purl":"pkg:pypi/irrd","source":"GHSA-22m3-c7vp-49fj"}],"prev":{"headline":"Ghostfolio: Full-Read SSRF in Manual Asset Import","id":"CVE-2026-28680"},"products":["irrd"],"published":"2026-03-06","related":[{"cvss_score":7.5,"headline":"Insufficient password hash filtering in some IRRd queries and exports","id":"CVE-2022-24798","kev_date_added":null,"published":"2022-03-31"}],"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":"PyPA Advisory Database","prefix":"PYSEC"},{"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":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-03-06","vendors":["irrdnet"]},"summary":"Attackers can poison password reset links via Host header injection to steal tokens and take over user accounts, allowing modification of routing registry objects.","url":"https://insights.sbomify.com/CVE-2026-28681/"}
