A flaw was found in libssh. Incorrect AES-GCM finalization checks in builds using the OpenSSL backend can effectively remove integrity protection, allowing an in-path attacker to modify plaintext on the wire without detection.

CVE-2026-1039325.8 MÉD—
——0ModSecurity is an open source, cross platform web application firewall (WAF) engine for Apache, IIS and Nginx. From 3.0.5 until 3.0.17, the PCRE2 implementation of @rxGlobal in src/utils/regex.cc converts pcre2_match match-limit errors into an ordinary no-match result instead of propagating a non-OK RegexResult. When attacker-controlled input exhausts SecPcreMatchLimit, rules that rely on MSC_PCRE_LIMITS_EXCEEDED or its TX compatibility indicator do not run, so a request that should be rejected can pass through the WAF. The issue affects PCRE2 deployments that use @rxGlobal with a limit-exhaustible expression and a compensating rule; it is not a universal WAF bypass. This issue is fixed in version 3.0.17.11hCVE-2026-855446.1 MÉD35.5%
——11Some Hikvision intercom products utilize an immutable factory value which should be obtained from local network or physical interaction with the device within their main card, which may allow attackers to forge a legitimate main card, thereby gaining the permission to issue cards.49dCVE-2026-156867.2 ALT65.4%
——20Adminer multi_query Incorrect Check of Function Return Value Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of Adminer. Authentication is required to exploit this vulnerability.
The specific flaw exists within the multi_query method. The issue results from an incorrect check of a function return value. An attacker can leverage this vulnerability to execute code in the context of the web server. Was ZDI-CAN-28201.11dCVE-2026-530907.8 ALT3.5%
——1In the Linux kernel, the following vulnerability has been resolved:
bpf: Fix ld_{abs,ind} failure path analysis in subprogs
Usage of ld_{abs,ind} instructions got extended into subprogs some time
ago via commit 09b28d76eac4 ("bpf: Add abnormal return checks."). These
are only allowed in subprograms when the latter are BTF annotated and
have scalar return types.
The code generator in bpf_gen_ld_abs() has an abnormal exit path (r0=0 +
exit) from legacy cBPF times. While the enforcement is on scalar return
types, the verifier must also simulate the path of abnormal exit if the
packet data load via ld_{abs,ind} failed.
This is currently not the case. Fix it by having the verifier simulate
both success and failure paths, and extend it in similar ways as we do
for tail calls. The success path (r0=unknown, continue to next insn) is
pushed onto stack for later validation and the r0=0 and return to the
caller is done on the fall-through side.17dCVE-2026-5818—15.8%
——5Incorrect check of function return value in Caliptra Core Runtime Firmware (ActivateFirmwareCmd::activate_fw modules) allows bypass of Caliptra Core's verification of the MCU FW during a hitless update.
This issue affects Core Runtime Firmware: from 2.0.0 through 2.0.1, 2.1.0.11dCVE-2026-464197.5 ALT23.7%
——7Yubico webauthn-server-core (aka java-webauthn-server) 2.8.0 before 2.8.2 incorrectly checks a function's return value in the second factor flow, leading to impersonation.11d
