CVE-2026-58188 is a high-severity vulnerability affecting several experimental plugins in Apache Traffic Server. The flaw class is described as a combination of memory-safety and limit-bypass errors, with available classification indicating an out-of-bounds write condition. The issue affects Apache Traffic Server versions 8.0.0 through 8.1.9, 9.0.0 through 9.2.14, and 10.0.0 through 10.1.3. Specific vulnerable plugin functions or code paths are not identified in the available information, but the defect resides in experimental plugin components rather than the core proxy alone. Successful exploitation could corrupt memory and bypass intended operational limits or safety checks within affected plugin logic.
