In verions 3.7.2 and 3.7.3, Dde to incorrect use of a default URL, `singularity` action commands (`run`/`shell`/`exec`) specifying a container using a `library://` URI will always attempt to retrieve the container from the default remote endpoint (`cloud.sylabs.io`) rather than the configured remote endpoint. An attacker may be able to push a malicious container to the default remote endpoint with a URI that is identical to the URI used by a victim with a non-default remote endpoint, thus executing the malicious container. Only action commands (`run`/`shell`/`exec`) against `library://` URIs are affected. Other commands such as `pull` / `push` respect the configured remote endpoint. The vulnerability is patched in Singularity version 3.7.4. Two possible workarounds exist: Users can only interact with the default remote endpoint, or an installation can have an execution control list configured to restrict execution to containers signed with specific secure keys.",null,[],[],[],[14],{"_key":15},"CVE-2021-32635",[],[],[],"2021-05-28T21:15:00Z","2026-05-20T16:04:58.584420791Z",{"cisa_kev":22,"cisa_ransomware":22,"cisa_vendor":9,"epss_severity":9,"epss_score":9,"severity":9,"severity_score":9,"severity_version":9,"severity_source":9,"severity_vector":9,"severity_status":9},false,[24,30,34,38],{"url":25,"sources":26,"tags":28},"https://ubuntu.com/security/CVE-2021-32635",[27],"osv_ubuntu",[29],"REPORT",{"url":31,"sources":32,"tags":33},"https://github.com/hpcng/singularity/security/advisories/GHSA-jq42-hfch-42f3",[27],[29],{"url":35,"sources":36,"tags":37},"https://github.com/sylabs/singularity/security/advisories/GHSA-5mv9-q7fq-9394",[27],[29],{"url":39,"sources":40,"tags":41},"https://www.cve.org/CVERecord?id=CVE-2021-32635",[27],[29],[],[],[45],{"source":27,"cvss_v2_0":9,"cvss_v3_0":9,"cvss_v3_1":46,"cvss_v4_0":9},{"baseScore":47,"baseSeverity":9,"vectorString":48,"impactScore":49,"exploitabilityScore":50},6.3,"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:L/I:L/A:L",5.7,7.2,[52],{"ecosystem":53,"name":54,"vendor":55,"product":54,"cpe_part":9,"purl_type":56,"purl_namespace":55,"purl_name":54,"source":9,"versions":57},"Ubuntu","singularity-container","ubuntu","deb",[58,62,63],{"version":59,"is_range":60,"range_type":61,"version_start":9,"version_start_type":9,"version_end":9,"version_end_type":9,"fixed_in":9},"all",true,"ecosystem",{"version":59,"is_range":60,"range_type":61,"version_start":9,"version_start_type":9,"version_end":9,"version_end_type":9,"fixed_in":9},{"version":59,"is_range":60,"range_type":61,"version_start":9,"version_start_type":9,"version_end":9,"version_end_type":9,"fixed_in":9}]
