CVE-2026-825977.4 HIG

—

———A vulnerability was identified in TOTOLINK NR1800X 9.1.0u.6681_B20230703. This affects the function setUssd of the file /cgi-bin/cstecgi.cgi. The manipulation of the argument ussd leads to command injection. The attack can be initiated remotely. The exploit is publicly available and might be used.4h CVE-2026-825957.4 HIG

—

———A vulnerability was found in D-Link DIR-825M 1.1.8. Affected by this vulnerability is the function sub_456CF4 of the file /boafrm/formSysCmd of the component System Command Execution. Performing a manipulation of the argument sysCmd results in command injection. It is possible to initiate the attack remotely. The exploit has been made public and could be used.5h CVE-2026-81319—

———Deserialization of Untrusted Data vulnerability in ash-project ash_cloak allows an attacker who can influence the bytes of an encrypted column to crash the BEAM node, by triggering unbounded atom creation or a decompression bomb during decryption. AshCloak.Calculations.Decrypt decodes the decrypted binary with Ash.Helpers.non_executable_binary_to_term/1 without the :safe option, so atoms in the payload are interned during the decode and never garbage collected, and the term format's compressed form is inflated transparently. vault.decrypt!() is the only barrier and stops tampering only for an authenticated cipher. Cloak also ships the unauthenticated AES.CTR, whose ciphertext an attacker who knows their own plaintext can XOR into any same-length payload without the key, so an ordinary read of the forged column reaches the decoder. A few hundred kilobytes of distinct atoms exhausts the atom table, or a small compressed payload inflates to gigabytes. This issue affects ash_cloak: from 0.1.0 before 0.4.0.11h CVE-2026-765476.6 MED

——5The User Profile Builder WordPress plugin before 4.0.1 does not validate the type of data being deserialized when importing a configuration file, allowing high privilege users such as administrators to conduct PHP Object Injection. The affected feature is a free add-on which is disabled by default, and no POP chain is present in the User Profile Builder WordPress plugin before 4.0.1 itself, so further impact requires a suitable gadget from another installed User Profile Builder WordPress plugin before 4.0.1 or .1d CVE-2026-55220—

——12Pimcore is an Open Source Data & Experience Management Platform. Prior to 11.5.19, 12.3.10, and 2026.1.6, Pimcore\Model\DataObject\ClassDefinition\Data\Hotspotimage::getDataFromResource() in models/DataObject/ClassDefinition/Data/Hotspotimage.php passes the field __hotspots object-store column to Pimcore\Tool\Serialize::unserialize() without an allowed-classes restriction after JSON decoding fails. An attacker with a separate capability to write crafted PHP serialized bytes into that column can instantiate available classes and trigger magic methods when an affected DataObject is loaded, which can produce arbitrary file writes or code execution through bundled gadget chains. The related ImageGallery, Block, and Video callers use the same fallback pattern, but the identified June fix changes the Hotspotimage caller only. This issue is fixed for Hotspotimage in versions 11.5.19, 12.3.10, and 2026.1.6.2d CVE-2026-817577.2 HIG
