CVE-2026-31842
Last modified
CVE-2026-31842 is a high-severity vulnerability rated 8.7/10 on the CVSS scale. 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.. EPSS estimates a 0.90% chance of exploitation in the next 30 days.
