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-2026-104891/ (Markdown: https://insights.sbomify.com/CVE-2026-104891/index.md)","id":"CVE-2026-104891","markdown":"https://insights.sbomify.com/CVE-2026-104891/index.md","name":"CVE-2026-104891","record":{"aliases":["GHSA-jg6q-3qfh-r9f8"],"analysis":null,"analysis_generated_by":null,"assigner":"GitHub_M","cpe":[],"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-863","name":"Incorrect Authorization"},{"id":"CWE-290","name":"Authentication Bypass by Spoofing"}],"description":"mppx-condition-gate provides conditional free-access wrappers for mppx payment methods. Prior to @insumermodel/mppx-condition-gate 3.0.0 and @insumermodel/mppx-token-gate 1.0.4, the packages read a wallet address from the client-supplied credential.source, checked whether that public address met configured on-chain conditions, and returned a successful free-access receipt without invoking the wrapped payment verifier or proving that the caller controlled the wallet. An unauthenticated attacker could name any qualifying wallet and obtain content that should require payment, and cached grants could be reused for the configured cache lifetime. The corrected packages prevent free-access authorization unless payer control has been established. These issues are fixed in @insumermodel/mppx-condition-gate 3.0.0 and @insumermodel/mppx-token-gate 1.0.4.","ecosystems":["npm"],"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":"mppx-condition-gate: Free-access path grants on a self-declared wallet without proving control","id":"CVE-2026-104891","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"npm","product":null,"products":[],"type":null,"year":"2026"},"n_packages":4,"n_references":3,"next":{"headline":"Plane: Plaintext logging of API token","id":"CVE-2026-104892"},"packages":[{"ecosystem":"npm","fixed":["3.0.0"],"introduced":["0"],"last_affected":[],"package":"@insumermodel/mppx-condition-gate","purl":null,"source":"GHSA-jg6q-3qfh-r9f8"},{"ecosystem":"npm","fixed":["3.0.0"],"introduced":["0"],"last_affected":[],"package":"@insumermodel/mppx-condition-gate","purl":"pkg:npm/%40insumermodel/mppx-condition-gate","source":"GHSA-jg6q-3qfh-r9f8"},{"ecosystem":"npm","fixed":["1.0.4"],"introduced":["0"],"last_affected":[],"package":"@insumermodel/mppx-token-gate","purl":null,"source":"GHSA-jg6q-3qfh-r9f8"},{"ecosystem":"npm","fixed":["1.0.4"],"introduced":["0"],"last_affected":[],"package":"@insumermodel/mppx-token-gate","purl":"pkg:npm/%40insumermodel/mppx-token-gate","source":"GHSA-jg6q-3qfh-r9f8"}],"prev":{"headline":"Kunstmaan CMS: MediaBundle extension blacklist bypass allows authenticated administrators to upload executable PHP files leading to remote code execution","id":"CVE-2026-104890"},"products":["mppx-condition-gate","mppx-token-gate"],"published":"2026-10-05","related":[],"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":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"yes","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-10-05","vendors":["@insumermodel","douglasborthwick-crypto"]},"summary":null,"url":"https://insights.sbomify.com/CVE-2026-104891/"}
