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-2026-28342 exists.\n\nAffected packages and fixed versions:\n- github.com/OliveTin/OliveTin (Go): affected all versions; fixed in 0.0.0-20260227002407-2eb5f0ba79d4\n- github.com/OliveTin/OliveTin (Go): affected all versions; fixed in 0.0.0-20260227002407-2eb5f0ba79d4\n- github.com/OliveTin/OliveTin (Go): affected all versions; fixed in 0.0.0-20260227002407-2eb5f0ba79d4\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-2026-28342/ (Markdown: https://insights.sbomify.com/CVE-2026-28342/index.md)","id":"CVE-2026-28342","markdown":"https://insights.sbomify.com/CVE-2026-28342/index.md","name":"CVE-2026-28342","record":{"aliases":["GHSA-pc8g-78pf-4xrp","GO-2026-4584"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"OliveTin web interface","requires_auth":"none","summary":"Unauthenticated attackers can cause denial of service in OliveTin by exhausting memory via concurrent requests to the PasswordHash API endpoint.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"olivetin","vendor":"olivetin"}],"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:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-770","name":"Allocation of Resources Without Limits or Throttling"},{"id":"CWE-400","name":"Uncontrolled Resource Consumption"}],"description":"OliveTin gives access to predefined shell commands from a web interface. Prior to version 3000.10.2, the PasswordHash API endpoint allows unauthenticated users to trigger excessive memory allocation by sending concurrent password hashing requests. By issuing multiple parallel requests, an attacker can exhaust available container memory, leading to service degradation or complete denial of service (DoS). The issue occurs because the endpoint performs computationally and memory-intensive hashing operations without request throttling, authentication requirements, or resource limits. This issue has been patched in version 3000.10.2.","ecosystems":["Go"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"weaponised"},"has_fix":true,"headline":"OliveTin: Unauthenticated Denial of Service via Memory Exhaustion in PasswordHash API Endpoint","id":"CVE-2026-28342","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Go","product":null,"products":[],"type":"denial_of_service","year":"2026"},"n_packages":3,"n_references":3,"next":{"headline":"CKEditor: Cross-site scripting (XSS) in the HTML Support package","id":"CVE-2026-28343"},"packages":[{"ecosystem":"Go","fixed":["0.0.0-20260227002407-2eb5f0ba79d4"],"introduced":["0"],"last_affected":[],"package":"github.com/OliveTin/OliveTin","purl":null,"source":"GHSA-pc8g-78pf-4xrp"},{"ecosystem":"Go","fixed":["0.0.0-20260227002407-2eb5f0ba79d4"],"introduced":["0"],"last_affected":[],"package":"github.com/OliveTin/OliveTin","purl":"pkg:golang/github.com/OliveTin/OliveTin","source":"GHSA-pc8g-78pf-4xrp"},{"ecosystem":"Go","fixed":["0.0.0-20260227002407-2eb5f0ba79d4"],"introduced":["0"],"last_affected":[],"package":"github.com/OliveTin/OliveTin","purl":"pkg:golang/github.com/OliveTin/OliveTin","source":"GO-2026-4584"}],"prev":{"headline":"PMD Designer has Stored XSS in VBHTMLRenderer and YAHTMLRenderer via unescaped violation messages","id":"CVE-2026-28338"},"products":["OliveTin"],"published":"2026-03-05","related":[{"cvss_score":10,"headline":"OliveTin: OS Command Injection via `password` argument type and webhook JSON extraction bypasses shell safety checks","id":"CVE-2026-27626","kev_date_added":null,"published":"2026-02-25"},{"cvss_score":8.8,"headline":"OliveTin: JWT Audience Validation Bypass in Local Key and HMAC Modes","id":"CVE-2026-30223","kev_date_added":null,"published":"2026-03-06"},{"cvss_score":8.5,"headline":"OliveTin's unsafe parsing of UniqueTrackingId can be used to write files","id":"CVE-2026-31817","kev_date_added":null,"published":"2026-03-10"},{"cvss_score":7.5,"headline":"OliveTin: Unauthenticated DoS via concurrent map writes in OAuth2 state handling","id":"CVE-2026-28789","kev_date_added":null,"published":"2026-03-05"},{"cvss_score":7.5,"headline":"OliveTin: Unauthenticated Action Termination via KillAction When Guests Must Login","id":"CVE-2026-28790","kev_date_added":null,"published":"2026-03-05"},{"cvss_score":7.1,"headline":"OliveTin Unauthorized Action Output Disclosure via EventStream","id":"CVE-2026-32102","kev_date_added":null,"published":"2026-03-11"}],"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":"CC BY 4.0","name":"Go Vulnerability Database","prefix":"GO"},{"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":"2026-03-06","vendors":["OliveTin"]},"summary":"Unauthenticated attackers can cause denial of service in OliveTin by exhausting memory via concurrent requests to the PasswordHash API endpoint.","url":"https://insights.sbomify.com/CVE-2026-28342/"}
