Descrição técnica

JQ::Lite versions before 2.51 for Perl execute Perl code embedded in a query's regular expression by compiling it with string eval. The pattern given to test(), match(), or the match and =~ conditions of select() is placed in a `qr'...'` literal and compiled as source text, so a `(?{ ... })` code block in it runs without `use re 'eval'`. Single quotes in the pattern are escaped, but a code block runs in place and needs none. An attacker who supplies a query, or text that an application inserts into the pattern of one, can execute arbitrary Perl code in the calling process.

——3PyMoDAQ before 4.4.13, and pymodaq_data, pymodaq_gui, and pymodaq_utils before 5.1.15, 5.2.x before 5.2.14, and 5.3.x before 5.3.10, contain deserialization of untrusted data and eval injection vulnerabilities that allow attackers to execute arbitrary code by supplying crafted files that a user opens. Attackers can store pickled objects in HDF5 string nodes that StringARRAY.array_to_string() passes to pickle.loads() when the node is browsed or read, place Python expressions in HDF5 attributes that JsonConverter.json2object() evaluates, supply a .dock file that load_layout_state() unpickles from the Dashboard Load layout action, or embed Python expressions in XML settings files that elt_to_dict() and set_txt_from_elt() evaluate.2d CVE-2026-1204997.8 ALT

——11h5io before 0.2.6 contains a code injection vulnerability in read_hdf5() that allows attackers to execute arbitrary code by supplying a crafted HDF5 file. Attackers can store Python code in a node titled timezone, which _triage_read() passes to eval() with builtins reachable, name an arbitrary module in class or custom-object nodes that _import_class() imports, or place pickled objects in pd_dataframe or pd_series nodes that pandas deserializes on read.2d CVE-2026-114424—

——5SEPPmail Secure Email Gateway before 15.1.1 can evaluate attacker-influenced replacement text as Perl code in sender or recipient replacement rules. An unauthenticated remote sender can execute operating-system commands in the mail-processing worker context when an active rule uses message-derived replacement data and its search condition matches. The validated worker context was root.3d CVE-2026-443446.6 MÉD

——8Chamilo LMS is an open-source learning management system. In the 1.x line before 1.11.40, and the 2.x line before 2.0.1, multiple `eval()` calls in the vendored PEAR `HTML_QuickForm` libraries can execute arbitrary PHP code if form element names contain attacker-influenced data. Standard Chamilo forms use hardcoded element names; exploitation requires a developer-specific plugin or misconfiguration that lets user input reach those element names. Where that conditional path exists, the impact can be full server compromise. This issue is fixed in versions 1.11.40 and 2.0.1.3d CVE-2026-1159439.8 CRÍ

——15Spreadsheet::XLSX versions before 0.19 for Perl allow code execution via string eval of number format conditions in ExcelFmt. When a number format has a condition such as [>100], ExcelFmt chooses the format section by passing the condition and the cell value to a string eval. Both come from the workbook, and the eval runs while Spreadsheet::XLSX->new parses it. An attacker who supplies an XLSX file can run arbitrary Perl code.2d CVE-2026-908726.6 MÉD

——6Improper neutralization of directives in dynamically evaluated code in the Manager web console of Progress Software WS_FTP Server versions prior to 2024.0.7 and 2025.0.4 on Windows could allow an authenticated Manager administrator to execute arbitrary commands with the privileges of the WS_FTP Server IIS worker process.8d
