An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-32632 exists.\n\nAffected packages and fixed versions:\n- glances (PyPI): affected all versions; fixed in 4.5.2\n- glances (PyPI): affected all versions; fixed in 4.5.2\n- Glances (PyPI): affected all versions; fixed in 4.5.2\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-2026-32632/ (Markdown: https://insights.sbomify.com/CVE-2026-32632/index.md)","id":"CVE-2026-32632","markdown":"https://insights.sbomify.com/CVE-2026-32632/index.md","name":"CVE-2026-32632","record":{"aliases":["DEBIAN-CVE-2026-32632","GHSA-hhcg-r27j-fhv9","PYSEC-2026-2171","UBUNTU-CVE-2026-32632"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["data_read","data_modify"],"network_reachable":"yes","non_default_config":false,"product_category":"System monitoring tool","requires_auth":"none","summary":"Attackers can bypass same-origin policy via DNS rebinding to access Glances REST API and WebUI, allowing unauthorized data access or modification.","user_interaction":"required","vuln_class":"security_feature_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"glances","vendor":"nicolargo"}],"cvss":{"score":5.9,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:U/C:H/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-346","name":"Origin Validation Error"}],"description":"Glances is an open-source system cross-platform monitoring tool. Glances recently added DNS rebinding protection for the MCP endpoint, but prior to version 4.5.2, the main REST/WebUI FastAPI application still accepts arbitrary `Host` headers and does not apply `TrustedHostMiddleware` or an equivalent host allowlist. As a result, the REST API, WebUI, and token endpoint remain reachable through attacker-controlled domains in classic DNS rebinding scenarios. Once the victim browser has rebound the attacker domain to the Glances service, same-origin policy no longer protects the API because the browser considers the rebinding domain to be the origin. This is a distinct issue from the previously reported default CORS weakness. CORS is not required for exploitation here because DNS rebinding causes the victim browser to treat the malicious domain as same-origin with the rebinding target. Version 4.5.2 contains a patch for the issue.","ecosystems":["PyPI"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"weaponised"},"has_fix":true,"headline":"Glances's REST/WebUI Lacks Host Validation and Remains Exposed to DNS Rebinding","id":"CVE-2026-32632","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"PyPI","product":null,"products":[],"type":"security_feature_bypass","year":"2026"},"n_packages":3,"n_references":3,"next":{"headline":"Glances's Browser API Exposes Reusable Downstream Credentials via `/api/4/serverslist`","id":"CVE-2026-32633"},"packages":[{"ecosystem":"PyPI","fixed":["4.5.2"],"introduced":["0"],"last_affected":[],"package":"Glances","purl":null,"source":"GHSA-hhcg-r27j-fhv9"},{"ecosystem":"PyPI","fixed":["4.5.2"],"introduced":["0"],"last_affected":[],"package":"glances","purl":"pkg:pypi/glances","source":"GHSA-hhcg-r27j-fhv9"},{"ecosystem":"PyPI","fixed":["4.5.2"],"introduced":["0"],"last_affected":[],"package":"glances","purl":"pkg:pypi/glances","source":"PYSEC-2026-2171"}],"prev":{"headline":"Git for Windows: `git clone` from manipulated repositories can leak NTLM hashes to arbitrary servers","id":"CVE-2026-32631"},"products":["glances"],"published":"2026-03-18","related":[{"cvss_score":9.1,"headline":"Glances's Browser API Exposes Reusable Downstream Credentials via `/api/4/serverslist`","id":"CVE-2026-32633","kev_date_added":null,"published":"2026-03-18"},{"cvss_score":8.7,"headline":"Glances exposes the REST API without authentication","id":"CVE-2026-32596","kev_date_added":null,"published":"2026-03-18"},{"cvss_score":8.7,"headline":"Glances Exposes Unauthenticated Configuration Secrets","id":"CVE-2026-30928","kev_date_added":null,"published":"2026-03-10"},{"cvss_score":8.1,"headline":"Glances's Default CORS Configuration Allows Cross-Origin Credential Theft","id":"CVE-2026-32610","kev_date_added":null,"published":"2026-03-18"},{"cvss_score":8.1,"headline":"Glances Central Browser Autodiscovery Leaks Reusable Credentials to Zeroconf-Spoofed Servers","id":"CVE-2026-32634","kev_date_added":null,"published":"2026-03-18"},{"cvss_score":7.8,"headline":"Glances Vulnerable to Command Injection via Dynamic Configuration Values","id":"CVE-2026-33641","kev_date_added":null,"published":"2026-04-02"},{"cvss_score":7.7,"headline":"Glances Vulnerable to Cross-Origin Information Disclosure via Unauthenticated REST API (/api/4) due to Permissive CORS","id":"CVE-2026-34839","kev_date_added":null,"published":"2026-04-20"}],"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":"PyPA Advisory Database","prefix":"PYSEC"},{"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":"no","exploitation":"poc","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-03-18","vendors":["nicolargo"]},"summary":"Attackers can bypass same-origin policy via DNS rebinding to access Glances REST API and WebUI, allowing unauthorized data access or modification.","url":"https://insights.sbomify.com/CVE-2026-32632/"}
