Adminer 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.

——8A 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.7dCVE-2026-530907.8 ALT3.7%
——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.23dCVE-2026-350918.2 ALT56.6%
——17A flaw was found in Corosync. A remote unauthenticated attacker can exploit a wrong return value vulnerability in the Corosync membership commit token sanity check by sending a specially crafted User Datagram Protocol (UDP) packet. This can lead to an out-of-bounds read, causing a denial of service (DoS) and potentially disclosing limited memory contents21dCVE-2023-45019.8 CRÍ47.7%
——14User authentication with username and password credentials is ineffective in OpenText (Micro Focus) Visual COBOL, COBOL Server, Enterprise Developer, and Enterprise Server (including product variants such as Enterprise Test Server), versions 7.0 patch updates 19 and 20, 8.0 patch updates 8 and 9, and 9.0 patch update 1, when LDAP-based authentication is used with certain configurations. When the vulnerability is active, authentication succeeds with any valid username, regardless of whether the password is correct; it may also succeed with an invalid username (and any password). This allows an attacker with access to the product to impersonate any user.
Mitigations: The issue is corrected in the upcoming patch update for each affected product. Product overlays and workaround instructions are available through OpenText Support. The vulnerable configurations are believed to be uncommon.
Administrators can test for the vulnerability in their installations by attempting to sign on to a Visual COBOL or Enterprise Server component such as ESCWA using a valid username and incorrect password.38d
