CVE-2026-77220: Expired Pointer Dereference in michaelrsweet pdfioCVE-2026-77220 0 PDFio versions prior to 1.6.5 contain a dangling pointer vulnerability in the dictionary string-formatting function. This flaw involves storing a pointer to a stack-local buffer in the document dictionary without copying the string value. In multi-threaded or pooled-request environments, this can lead to stack memory reuse across requests, causing silent corruption of document content by overwriting one caller's dictionary string values with another's data.
