Jan 22, 2026A flaw was found in SIPp.CVE-2026-0710 · Other software · reported by patrick@puiterwijk.orgHigh 8.4
A flaw was found in SIPp. A remote attacker could exploit this by sending specially crafted Session Initiation Protocol (SIP) messages during an active call. This vulnerability, a NULL pointer dereference, can cause the application to crash, leading to a denial of service. Under specific conditions, it may also allow an attacker to execute unauthorized code, compromising the system's integrity and availability.

Nov 18, 2020Kamailio before 5.4.0, as used in Sip Express Router (SER) in Sippy Softswitch 4.5 through 5.2 and other products, allows a bypass of a header-removal protectioCVE-2020-28361 · Other software · Kamailio · reported by MITREMedium 5.4
Kamailio before 5.4.0, as used in Sip Express Router (SER) in Sippy Softswitch 4.5 through 5.2 and other products, allows a bypass of a header-removal protection mechanism via whitespace characters. This occurs in the remove_hf function in the Kamailio textops module. Particular use of remove_hf in Sippy Softswitch may allow skilled attacker having a valid credential in the system to disrupt internal call start/duration accounting mechanisms leading potentially to a loss of revenue.

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.
