Last modified Jun 17, 2026

CVE-2022-40299 is a high-severity vulnerability rated 7.8/10 on the CVSS scale. In Singular before 4.3.1, a predictable /tmp pathname is used (e.g., by sdb.cc), which allows local users to gain the privileges of other users via a procedure in a file under /tmp. NOTE: this CVE Record is about sdb.cc and similar files in the Singular interface that have predictable /tmp pathnames; this CVE Record is not about the lack of a safe temporary-file creation capability in the Singular language.. EPSS estimates a 0.31% chance of exploitation in the next 30 days.
