BC-JAVA, published on 15 Apr 2026. An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-0636 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- org.bouncycastle:bcprov-jdk14 (Maven): affected from 1.74; fixed in 1.84\n- org.bouncycastle:bcprov-jdk14 (Maven): affected from 1.74; fixed in 1.84\n- org.bouncycastle:bcprov-jdk15to18 (Maven): affected from 1.74; fixed in 1.84\n- org.bouncycastle:bcprov-jdk15to18 (Maven): affected from 1.74; fixed in 1.84\n- org.bouncycastle:bcprov-jdk18on (Maven): affected from 1.74; fixed in 1.84\n- org.bouncycastle:bcprov-jdk18on (Maven): affected from 1.74; fixed in 1.84\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-2026-0636/ (Markdown: https://insights.sbomify.com/CVE-2026-0636/index.md)","id":"CVE-2026-0636","markdown":"https://insights.sbomify.com/CVE-2026-0636/index.md","name":"CVE-2026-0636","record":{"aliases":["CLEANSTART-2026-FV35085","CLEANSTART-2026-GK94904","CLSA-2026-1787930356","DEBIAN-CVE-2026-0636","ECHO-4873-562c-433e","GHSA-c3fc-8qff-9hwx","MINI-27w8-5g29-33m3","MINI-2fgw-5h7j-x6qp","MINI-39j5-whcg-jgp2","MINI-46pv-rmmx-9cx4","MINI-4qrm-h6c9-v3gf","MINI-4v4p-h8g3-fpr7","MINI-53j4-9c8w-pg7c","MINI-5jvx-jh47-h63c","MINI-5qh8-jpr2-mjc4","MINI-63r6-7869-3px6","MINI-6cj7-52wg-cv37","MINI-6f3r-j967-4268","MINI-6pg4-q4p2-m2j2","MINI-6pqx-wvch-fgpc","MINI-73fv-wq6h-9p94","MINI-79jj-93qf-jrr6","MINI-86hh-pxpf-mcpm","MINI-8rf8-3gxw-78vj","MINI-96gf-f7v9-32xf","MINI-c6fq-w67q-qfr3","MINI-cc9v-qrp4-jg27","MINI-chqm-2mwm-8qqc","MINI-cjw8-qf6m-234c","MINI-cmwj-3c64-4f3h","MINI-cwpq-9346-wg7h","MINI-f2x3-qc79-jpxg","MINI-f4cx-ccr2-4jp8","MINI-fm8g-whmf-fv8x","MINI-g24j-936w-3396","MINI-g53m-5w68-gq39","MINI-grj7-g5gv-jjqw","MINI-h6g7-mr5r-9jxg","MINI-hm4h-972r-9w3r","MINI-j29q-j82j-vmg3","MINI-j2fr-8p8x-7r9h","MINI-j3m5-5278-hmc8","MINI-m8w4-qq9w-5cfw","MINI-pgc4-8fgw-2xqw","MINI-pq6w-w6rc-44rh","MINI-q3wh-qj8c-mjqp","MINI-qj92-x9x7-rh8c","MINI-r5fr-w834-mccj","MINI-rq9x-hcxh-pf3r","MINI-rqg7-6gqm-q4r5","MINI-v7q3-9m82-86hr","MINI-vpmv-4hq2-whpm","MINI-vrgx-vhpj-3vpm","MINI-w4g5-8jpv-p27f","MINI-xh53-j7jr-p2p4","MINI-xpwf-x3c6-fp8x","ROOT-APP-MAVEN-CVE-2026-0636","UBUNTU-CVE-2026-0636"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["data_read","security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Java cryptography library","requires_auth":"none","summary":"An LDAP injection vulnerability in the Bouncy Castle Java library allows attackers to manipulate LDAP queries, potentially leading to unauthorized data access or bypassing security controls.","user_interaction":"not_required","vuln_class":"other"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"bcorg","cpe":[],"cvss":{"score":5.5,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N/E:P/S:N/AU:Y/R:A/RE:M/U:Amber","version":"4.0"},"cwes":[{"id":"CWE-90","name":"Improper Neutralization of Special Elements used in an LDAP Query"}],"description":"Improper neutralization of special elements used in an LDAP query ('LDAP injection') vulnerability in Legion of the Bouncy Castle Inc.
