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-2018-11565 in the wild and no public exploit code.\n\nAffected product: Mahara Mahara. 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-2018-11565/ (Markdown: https://insights.sbomify.com/CVE-2018-11565/index.md)","id":"CVE-2018-11565","markdown":"https://insights.sbomify.com/CVE-2018-11565/index.md","name":"CVE-2018-11565","record":{"aliases":["GHSA-fx2f-r5xx-vf9m"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"Mahara ePortfolio","requires_auth":"none","summary":"Mahara discloses registered usernames via mention functionality, allowing attackers to enumerate valid accounts.","user_interaction":"not_required","vuln_class":"information_disclosure"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"mahara","vendor":"mahara"}],"cvss":{"score":5.3,"severity":"medium","source":"nvd","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N","version":"3.0"},"cwes":[{"id":"CWE-200","name":"Exposure of Sensitive Information to an Unauthorized Actor"}],"description":"Mahara 17.04 before 17.04.8 and 17.10 before 17.10.5 and 18.04 before 18.04.1 are vulnerable to mentioning the usernames that are already taken by people registered in the system rather than masking that information.","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":"Information disclosure in n/a","id":"CVE-2018-11565","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"mahara:mahara","products":["mahara:mahara"],"type":"information_disclosure","year":"2018"},"n_packages":0,"n_references":2,"next":{"headline":"Information disclosure in n/a","id":"CVE-2018-11567"},"packages":[],"prev":{"headline":"Pagekit Stored Cross-site Scripting","id":"CVE-2018-11564"},"products":["n/a"],"published":"2018-05-30","related":[{"cvss_score":9.8,"headline":"Deserialization in n/a","id":"CVE-2022-45134","kev_date_added":null,"published":"2025-08-22"},{"cvss_score":9.8,"headline":"Command injection in n/a","id":"CVE-2022-44544","kev_date_added":null,"published":"2022-11-06"},{"cvss_score":9.8,"headline":"Auth bypass in n/a","id":"CVE-2021-40849","kev_date_added":null,"published":"2021-11-03"},{"cvss_score":9.8,"headline":"Auth bypass in n/a","id":"CVE-2017-1000152","kev_date_added":null,"published":"2017-11-03"},{"cvss_score":9.8,"headline":"Auth bypass in n/a","id":"CVE-2017-1000153","kev_date_added":null,"published":"2017-11-03"},{"cvss_score":9.8,"headline":"Auth bypass in n/a","id":"CVE-2017-1000154","kev_date_added":null,"published":"2017-11-03"},{"cvss_score":9.1,"headline":"Information disclosure in n/a","id":"CVE-2024-39335","kev_date_added":null,"published":"2025-08-26"}],"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":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-05","vendors":["n/a"]},"summary":"Mahara discloses registered usernames via mention functionality, allowing attackers to enumerate valid accounts.","url":"https://insights.sbomify.com/CVE-2018-11565/"}
