Jun 26, 2026An unauthenticated stack-based buffer overflow vulnerability exists in thttpd in GeoVision GV-LPC2011 and GV-LPC2211 V1.12 and earlier.CVE-2026-57878 · Other software · GeoVision Inc. · reported by 0df08a0e-a200-4957-9bb0-084f562506f9Critical 9.8
An unauthenticated stack-based buffer overflow vulnerability exists in thttpd in GeoVision GV-LPC2011 and GV-LPC2211 V1.12 and earlier. The vulnerability is caused by insufficient bounds checking when processing web request parameters in a specific request path. A remote attacker may exploit this vulnerability by sending a crafted HTTP request with overly long input, resulting in memory corruption, denial of service, or potentially arbitrary code execution.

Feb 7, 2021An issue was discovered in sthttpd through 2.27.1.CVE-2021-26843 · Other software · Sthttpd Project · reported by MITREHigh 7.5
An issue was discovered in sthttpd through 2.27.1. On systems where the strcpy function is implemented with memcpy, the de_dotdot function may cause a Denial-of-Service (daemon crash) due to overlapping memory ranges being passed to memcpy. This can triggered with an HTTP GET request for a crafted filename. NOTE: this is similar to CVE-2017-10671, but occurs in a different part of the de_dotdot function.

Multiple buffer overflows in htpasswd, as used in Acme thttpd 2.25b, and possibly other products such as Apache, might allow local users to gain privileges via (1) a long command line argument and (2) a long line in a file. NOTE: since htpasswd is normally installed as a non-setuid program, and the exploit is through command line options, perhaps this issue should not be included in CVE. However, if there are some typical or recommended configurations that use htpasswd with sudo privileges, or common products that access htpasswd remotely, then perhaps it should be included.

Where this comes from: the exploited list is CISA’s Known Exploited Vulnerabilities catalog. Everything else is the whole National Vulnerability Database, where each record is published by the team that found the bug (Wordfence, Patchstack, WPScan, the vendors themselves and others); we show who. Exploit odds are FIRST’s EPSS, updated daily. Titles and categories are ours, so check the linked record before acting on a detail. For a write-up of the big ones, see our advisories. Every vendor, and every WordPress plugin and theme with a recorded flaw, also has its own page. All of it is free to reuse as JSON, CSV or RSS.
