CVE-2026-53582 is a stored XPath injection vulnerability in OPNsense affecting certificate authority management functionality exposed through the trust and CA management API. The flaw arises because a user-controllable reference identifier field is incorporated into an XPath expression executed against the system configuration without sufficient validation or neutralization of XPath metacharacters. Specifically, the vulnerable logic performs an XPath lookup using attacker-influenced input when resolving references in the configuration data, allowing a low-privileged user with certificate-related management permissions to persist a crafted payload and later trigger XPath evaluation against config.xml. This enables extraction of sensitive configuration values through a boolean oracle exposed by API responses. Disclosed examples include private keys, password hashes, synchronization credentials, and API secrets stored in the configuration. The issue can result in privilege escalation and may create a path to remote code execution depending on the secrets exposed and the deployment context.

CVE-2026-55099 is a denial-of-service vulnerability in the Python icalendar library affecting versions 7.1.0, 7.1.1, and 7.1.2. The issue is caused by the Component.__eq__ implementation, which compares subcomponents with O(2^n) time complexity relative to nesting depth. Because the parser accepts arbitrarily nested calendar components, an attacker can supply a very small malicious .ics file containing deeply nested components that triggers pathological comparison behavior. A single equality-related operation on parsed attacker-controlled calendar data can then take minutes to complete or hang indefinitely. The vulnerable behavior can be reached through equality and membership operations including ==, !=, in, set or dict membership, deduplication logic, and test assertions that compare parsed components.

CVE-2024-13745 is a flaw in EDK II’s GPT measurement and parsing logic that allows the GUID Partition Table layout or metadata actually used by firmware to differ from what is measured into TPM PCR[5]. According to the disclosure, affected versions include EDK II releases up to and including edk2-stable202411, and later versions may also be affected because no fix was known at disclosure time. The issue arises from inconsistencies between DxeTpm2MeasureBootLib, which measures GPT data for TPM event logging, and PartitionDxe, which parses, validates, and may recover GPT structures for actual use. DxeTpm2MeasureBootLib reads the GPT header from LBA 1, applies comparatively relaxed validation, does not validate CRC32 checksums, does not consult the backup GPT header, and omits unused GPT partition entries from the measured structure. PartitionDxe, by contrast, performs stricter validation, reads both primary and backup GPT headers, and includes recovery logic. The disclosure further describes error-handling flaws in PartitionRestoreGptTable() and PartitionValidGptTable() where failures can leave PrimaryHeader populated with untrusted invalid data while execution continues down a path treating both GPT tables as valid. An attacker can exploit these discrepancies by preserving the GPT data that DxeTpm2MeasureBootLib measures while causing PartitionDxe to recover or use a different GPT header and partition entry array, including via malformed backup GPT headers and attacker-controlled AlternateLBA values. The result is a data-only integrity failure in which PCR[5] and TPM event logs can indicate an expected GPT state while firmware and the operating system use attacker-influenced partition layout or metadata.

CVE-2026-33224 affects Bisheng and is described in the provided reporting as an authenticated remote command execution vulnerability in Bisheng's MCP tool/server configuration functionality. The issue is tied to unsafe handling of Model Context Protocol (MCP) STDIO-based server configuration, where attacker-controlled command and argument values can be introduced into local process execution without adequate sanitization or restriction. In the reported exploitation pattern, a user able to access Bisheng's MCP configuration workflow can register or modify an MCP tool/server definition so that Bisheng launches an attacker-specified operating system command on the host running the application. The reporting places this issue in a broader family of MCP STDIO command-injection flaws propagated through unsafe SDK and application design. It also notes that Bisheng's open user registration lowers the barrier to obtaining the authenticated access needed for exploitation.

CVE-2021-35406 is a command injection vulnerability in the Prolink PRC2402M router, tested on firmware version 20190909. Based on the provided supporting content, the flaw is in the /cgi-bin/qos.cgi CGI handler. When the page parameter is set to qos, the qos_settings routine processes attacker-controlled parameters including qos_dat and qos_bandwidth, uses sprintf to embed them into shell command strings, and executes the resulting command via do_system, a wrapper around system, without sufficient input validation or sanitization. This allows arbitrary shell metacharacters or command substitution to be injected through HTTP POST parameters. The provided proof of concept uses a crafted POST request to /cgi-bin/qos.cgi with page=qos and a malicious qos_dat value such as $(echo gg>/tmp/gg) to demonstrate code execution.

CVE-2024-35347 is a vulnerability in AMD CPUs, specifically affecting the microcode signature verification process. The flaw allows systems to accept microcode updates that lack the critical microcode signing fix, leaving them exposed to potential exploitation. The vulnerability primarily impacts AMD Family 19h CPUs and is documented in AMD security bulletin AMD-SB-7033. The root cause is insufficient enforcement of microcode signature verification, which can only be fully remediated by applying a BIOS update that delivers the updated microcode with the signing fix. Without this update, systems remain vulnerable even if they receive microcode updates from the Linux firmware repository, as these do not address the underlying signature verification issue.
