Summary
The `flow/admin/moniteur.php` script in Use It Flow administration website before version 10.0.0 is vulnerable to Remote Code Execution. An attacker can supply unsanitized input via the `action` GET parameter, which after insufficient validation is executed by the `eval()` function. Although a `method_exists()` check is performed, it only validates the part before the first parenthesis `(`, allowing arbitrary PHP code to be appended after a valid method call.
Risk Assessment
An unauthenticated or trivially authenticated attacker can fully compromise the web server by executing arbitrary PHP code with the privileges of the web server process. This leads to complete loss of confidentiality, integrity, and availability of the system and its data.
Recommendation
Immediately upgrade Use It Flow to version 10.0.0 or later. If upgrading is not possible, temporarily block access to the `flow/admin/moniteur.php` script at the WAF or web server level.

A vulnerability was determined in EFM ipTIME C200E 1.094. The impacted element is an unknown function of the file iux_set.cgi of the component System Setup. This manipulation causes OS command injection. It is possible to initiate the attack remotely. The exploit has been publicly disclosed and may be utilized.
- CVE-2026-12944Critical
IBM Langflow OSS 1.0.0 through 1.10.0 allows attackers to execute arbitrary Python code with root privileges (UID=0) on the Langflow server by submitting components containing socket or urllib imports. This enables AWS credential theft via IMDSv1 SSRF, arbitrary file exfiltration from the container filesystem, and lateral movement to internal services (PostgreSQL, Redis) within the Docker network. The scanner incorrectly returns "validated": true, providing a false security signal.

Deserialization of untrusted data in WHMCS 9.0.0 before 9.0.8 and 8.0.0 before 8.13.7 allows remote attackers to execute arbitrary code.

An out-of-bounds write issue in Apple products was addressed with improved bounds checking. A remote attacker may be able to cause unexpected app termination or arbitrary code execution. This issue is fixed in iOS 26.7, iPadOS 26.7, iOS 27, iPadOS 27, macOS Golden Gate 27, macOS Sequoia 15.8, macOS Tahoe 26.7, tvOS 27, visionOS 27, and watchOS 27.
- CVE-2026-53713Critical
Envoy Gateway prior to 1.7.4 and 1.8.1 does not collapse redundant separators in to_absolute_normalized_path in internal/gatewayapi/luavalidator/security.lua before is_critical_path evaluates Lua submitted through EnvoyExtensionPolicy during default Strict validation. Linux resolves a double-slash absolute path as the corresponding single-slash path, but the validator does not match the redundant-separator form, allowing submitted Lua to read arbitrary files from the gateway controller pod. Exposed files can include Kubernetes service-account tokens, TLS certificates, and process environment data, and the disclosed credentials can provide access to sensitive Kubernetes API Server or Gateway xDS server information. This issue is fixed in versions 1.7.4 and 1.8.1.
- CVE-2026-55209Critical
resdata prior to 6.2.9 insufficiently validates numeric fields, grid dimensions, keyword sizes, and array indexes while parsing untrusted GRDECL files in lib/resdata/rd_kw_grdecl.cpp and lib/resdata/rd_grid.cpp. Malformed COORD, ZCORN, CORSNUM, ACTNUM, or MAPAXES data can reach rd_grid_alloc_GRDECL_kw__ with inconsistent lengths, while unbounded floating-point conversion can exceed the intended parser buffer. In a network service that accepts untrusted GRDECL files, these conditions can cause a classic buffer overflow, out-of-bounds reads, invalid array access, NULL pointer dereference, memory corruption, or service termination. This issue is fixed in version 6.2.9.
- CVE-2026-54334Critical
UEFI Firmware Parser prior to 1.14 has a flaw in ReadCLen() in uefi_firmware/compression/Tiano/Decompress.c where reading Number from GetBits(Sd, CBIT) with CBIT = 9 can obtain 511 entries for the 510-element Sd->mCLen heap array because its loop does not enforce Index < NC. The CharC == 2 run-length path can additionally request up to 531 zero writes through Sd->mCLen[Index++] = 0. Crafted Tiano or EFI compressed firmware can corrupt heap memory, deterministically crash the parsing process, and potentially execute code. This issue is fixed in version 1.14.
- CVE-2026-54333Critical
UEFI Firmware Parser prior to 1.14 has a flaw in MakeTable() in uefi_firmware/compression/Tiano/Decompress.c that does not validate that bit-length values read from a crafted Tiano or EFI compressed firmware bitstream remain within the expected range from 0 through 16. The parsing path CompressedSection.process() to efi_compressor.TianoDecompress() to TianoDecompress() to ReadPTLen() to MakeTable() can write beyond the stack-allocated Count[17] array and related decode tables. The resulting stack corruption deterministically crashes the parsing process and may permit code execution. This issue is fixed in version 1.14.
- CVE-2026-50006Critical
Anyquery prior to 0.4.5 forwards unauthenticated SQL from its MySQL-compatible server port to SQLite without restricting ATTACH DATABASE filesystem targets. A remote attacker can select any path writable by the Anyquery server process, cause SQLite to create a database file there, and place attacker-controlled table content in that file. This permits arbitrary file creation or overwrite, causing filesystem integrity loss and denial of service; remote code execution is possible only when another service interprets the written file or the process has a suitably privileged writable target. This issue is fixed in version 0.4.5.

IBM DataStage on Cloud Pak for Data 5.4.0.0 could allow a remote authenticated attacker to perform an arbitrary file write due to improper validation of file paths.
Original NVD description (English source)
The `flow/admin/moniteur.php` script in Use It Flow administration website before 10.0.0 is vulnerable to Remote Code Execution. When handling GET requests, the script takes user-supplied input from the `action` URL parameter, performs insufficient validation, and incorporates this input into a string that is subsequently executed by the `eval()` function. Although a `method_exists()` check is performed, it only validates the part of the user input *before* the first parenthesis `(`, allowing an attacker to append arbitrary PHP code after a valid method call structure. Successful exploitation allows an unauthenticated or trivially authenticated attacker to execute arbitrary PHP code on the server with the privileges of the web server process.
