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-2026-103878 in the wild and no public exploit code.\n\nAffected product: Apache Directory LDAP API. 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-2026-103878/ (Markdown: https://insights.sbomify.com/CVE-2026-103878/index.md)","id":"CVE-2026-103878","markdown":"https://insights.sbomify.com/CVE-2026-103878/index.md","name":"CVE-2026-103878","record":{"aliases":["DEBIAN-CVE-2026-103878","GHSA-vmxq-hqjm-cxv7","UBUNTU-CVE-2026-103878"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"LDAP API library","requires_auth":"none","summary":"Attackers can intercept sensitive data transmitted in plaintext during StartTLS operations in the Apache Directory LDAP API.","user_interaction":"not_required","vuln_class":"information_disclosure"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"apache","cpe":[],"cvss":{"score":7.5,"severity":"high","source":"cisa-adp","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-345","name":"Insufficient Verification of Data Authenticity"}],"description":"Cleartext transmission of sensitive information vulnerability in Apache Directory LDAP API.\n\nA StartTLS extended operation started after a Search request has been sent can lead to receive data in plain text before the TLS Handshake has been completed.\n\nThis issue affects Apache Directory LDAP API: from 2.1.0 before 2.1.9.\n\nUsers are recommended to upgrade to version 2.1.9, which fixes the issue.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":false,"headline":"Apache Directory LDAP API: Injection of plaintext responses during StartTLS","id":"CVE-2026-103878","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"information_disclosure","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Apache Directory LDAP API: Denial of service via excessive bcrypt cost factor in stored passwords","id":"CVE-2026-103880"},"packages":[],"prev":{"headline":"Apache Directory LDAP API: Unsafe loading of Java code from LDAP schema elements","id":"CVE-2026-103877"},"products":["Apache Directory LDAP API"],"published":"2026-10-02","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"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":["Apache Software Foundation"]},"summary":"Attackers can intercept sensitive data transmitted in plaintext during StartTLS operations in the Apache Directory LDAP API.","url":"https://insights.sbomify.com/CVE-2026-103878/"}
