There are 4 open security issues in trixie.
4 issues left for the package maintainer to handle:
- CVE-2026-38819:
(needs triaging)
Multiple memory leaks in openNDS before 11.0.0 allow an unauthenticated attacker on the captive portal network to exhaust all available memory on the device within minutes.
- CVE-2026-38820:
(needs triaging)
openNDS before 11.0.0 is susceptible to unauthenticated OS command execution via shell command injection through the fas query parameter on the /opennds_preauth/ endpoint because of libopennds.sh.
- CVE-2026-38821:
(needs triaging)
A heap-based buffer overflow vulnerability exists in openNDS before 11.0.0 that allows an unauthenticated attacker on the captive portal network to crash the openNDS daemon (denial of service) and potentially achieve remote code execution. This is in http_microhttpd.c.
- CVE-2026-38822:
(needs triaging)
In openNDS before 11.0.0, the client_params.sh script, invoked by the openNDS daemon to serve the authenticated client status page, is vulnerable to OS command injection through crafted HTTP GET query parameter keys. An authenticated captive portal user can inject arbitrary shell commands by embedding semicolons in a URL query parameter name.
You can find information about how to handle these issues in the security team's documentation.
