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-2026-33894 exists.\n\nAffected product: digitalbazaar forge. No package-level version data is available, so check the vendor advisory linked from the reference page.\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-2026-33894/ (Markdown: https://insights.sbomify.com/CVE-2026-33894/index.md)","id":"CVE-2026-33894","markdown":"https://insights.sbomify.com/CVE-2026-33894/index.md","name":"CVE-2026-33894","record":{"aliases":["CLEANSTART-2026-NK73842","CLEANSTART-2026-ZI53736","MINI-4fx3-46r7-9rwx","MINI-5rxg-2777-xw37","MINI-5w8g-7hj3-x7pf","MINI-646m-fh43-83qm","MINI-6697-8rx4-6wc5","MINI-75v3-xr2f-8q35","MINI-c89r-6hx3-3573","MINI-fr44-jpqw-8273","MINI-fwqq-h7hv-66ff","MINI-hr2v-fc7q-j8vq","MINI-jgxr-32vv-gm4x","MINI-m33p-qxcm-r9xf","MINI-m3mg-3rgp-gf4g","MINI-mjgf-8j57-fv66","MINI-qm72-q8p4-85c7","MINI-vjpc-9pj9-vfx9","MINI-w478-77c8-7vf3","MINI-xj5h-j367-f589","MINI-xqfj-422f-44fh","ROOT-APP-NPM-CVE-2026-33894","UBUNTU-CVE-2026-33894"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"JavaScript TLS library","requires_auth":"none","summary":"Attackers can forge RSA-PKCS#1 v1.5 signatures in node-forge by exploiting ASN.1 parsing flaws, bypassing signature verification.","user_interaction":"not_required","vuln_class":"other"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"forge","vendor":"digitalbazaar"}],"cvss":{"score":7.5,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:N","version":"3.1"},"cwes":[{"id":"CWE-347","name":"Improper Verification of Cryptographic Signature"},{"id":"CWE-20","name":"Improper Input Validation"}],"description":"Forge (also called `node-forge`) is a native implementation of Transport Layer Security in JavaScript. Prior to version 1.4.0, RSASSA PKCS#1 v1.5 signature verification accepts forged signatures for low public exponent keys (e=3). Attackers can forge signatures by stuffing “garbage” bytes within the ASN structure in order to construct a signature that passes verification, enabling Bleichenbacher style forgery. This issue is similar to CVE-2022-24771, but adds bytes in an addition field within the ASN structure, rather than outside of it.  Additionally, forge does not validate that signatures include a minimum of 8 bytes of padding as defined by the specification, providing attackers additional space to construct Bleichenbacher forgeries. Version 1.4.0 patches the issue.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"weaponised"},"has_fix":true,"headline":"Forge has signature forgery in RSA-PKCS due to ASN.1 extra field","id":"CVE-2026-33894","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"other","year":"2026"},"n_packages":0,"n_references":5,"next":{"headline":"Forge has signature forgery in Ed25519 due to missing S \u003e L check","id":"CVE-2026-33895"},"packages":[],"prev":{"headline":"Hardcoded credentials in Teamcenter V2312","id":"CVE-2026-33893"},"products":["forge"],"published":"2026-03-27","related":[{"cvss_score":9.8,"headline":"Prototype Pollution","id":"CVE-2020-7720","kev_date_added":null,"published":"2020-09-01"},{"cvss_score":8.7,"headline":"node-forge ASN.1 Unbounded Recursion","id":"CVE-2025-66031","kev_date_added":null,"published":"2025-11-26"},{"cvss_score":8.6,"headline":"CVE-2025-12816","id":"CVE-2025-12816","kev_date_added":null,"published":"2025-11-25"},{"cvss_score":7.5,"headline":"Forge has Denial of Service via Infinite Loop in BigInteger.modInverse() with Zero Input","id":"CVE-2026-33891","kev_date_added":null,"published":"2026-03-27"},{"cvss_score":7.5,"headline":"Forge has signature forgery in Ed25519 due to missing S \u003e L check","id":"CVE-2026-33895","kev_date_added":null,"published":"2026-03-27"},{"cvss_score":7.5,"headline":"Improper Verification of Cryptographic Signature in node-forge","id":"CVE-2022-24771","kev_date_added":null,"published":"2022-03-18"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"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":"2026-09-10","vendors":["digitalbazaar"]},"summary":"Attackers can forge RSA-PKCS#1 v1.5 signatures in node-forge by exploiting ASN.1 parsing flaws, bypassing signature verification.","url":"https://insights.sbomify.com/CVE-2026-33894/"}
