| CVE | Summary | Source | Max CVSS | EPSS % | Published | Updated |
|---|---|---|---|---|---|---|
| CVE-2026-55202 | Tinyproxy through 1.11.3, fixed in commit 09312a1, fails to properly validate the Host header during stathost detection, allowing unauthenticated attackers to access the stats page by injecting a matching Host header or bypass detection via port manipulation. Remote attackers can trigger unauthorized access to internal proxy statistics or misroute requests as transparent proxy connections to circumvent access controls. | [email protected] | 8.8 | 0.34% | 2026-06-17 | 2026-06-22 |
| CVE-2026-31842 | 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. By sending a request with Transfer-Encoding: Chunked, an unauthenticated remote attacker can cause Tinyproxy to misinterpret the request as having no body.

| CVE-2025-63938 | Tinyproxy through 1.11.2 contains an integer overflow vulnerability in the strip_return_port() function within src/reqs.c. | [email protected] | 6.5 | 0.22% | 2025-11-26 | 2026-06-17 |
| CVE-2023-49606 | A use-after-free vulnerability exists in the HTTP Connection Headers parsing in Tinyproxy 1.11.1 and Tinyproxy 1.10.0. A specially crafted HTTP header can trigger reuse of previously freed memory, which leads to memory corruption and could lead to remote code execution. An attacker needs to make an unauthenticated HTTP request to trigger this vulnerability. | [email protected] | 9.8 | 63.08% | 2024-05-01 | 2026-06-17 |
| CVE-2022-40468 | Potential leak of left-over heap data if custom error page templates containing special non-standard variables are used. Tinyproxy commit 84f203f and earlier use uninitialized buffers in process_request() function. | [email protected] | 7.5 | 1.37% | 2022-09-19 | 2026-06-17 |
| CVE-2017-11747 | main.c in Tinyproxy 1.8.4 and earlier creates a /run/tinyproxy/tinyproxy.pid file after dropping privileges to a non-root account, which might allow local users to kill arbitrary processes by leveraging access to this non-root account for tinyproxy.pid modification before a root script executes a "kill `cat /run/tinyproxy/tinyproxy.pid`" command. | [email protected] | 5.5 | 0.29% | 2017-07-30 | 2026-06-16 |
