Answer in brief
CVE-2026-31842 records a Unknown severity vulnerability in Tinyproxy HTTP request parsing desynchronization via case-sensitive Transfer-Encoding handling. The current sources do not mark it as known exploited. The current feed maps Tinyproxy Project/Tinyproxy (generic). Check affected ranges and fixed versions before updating.
Analysis pending evidence review
HOL Guard separates source facts from reviewed analysis. See the methodology.
A CVSS score is not reported in the current record. The current sources do not mark it as known exploited. Treat this as a source-backed prioritization signal, not a statement about your environment.

Tinyproxy through 1.11.3 is vulnerable to HTTP request parsing desynchronization due to a case-sensitive comparison of the Transfer-Encoding header in src/reqs.c. The is_chunked_transfer function uses strcmp to compare the header value against "chunked", even though RFC 7230 specifies that transfer-coding names are case-insensitive.
