CVE-2025-71358

CVE-2025-71358 concerns the Python tool picklescan (pre-0.0.29) failing to detect malicious pickle payloads that exploit the function idlelib.autocomplete.AutoComplete.get_entity in reduce methods. When a crafted pickle is loaded with pickle.load(), arbitrary commands can execute, enabling remote...

CVE-2025-71344 picklescan - Arbitrary Code Execution via Undetected ensurepip._run_pip Function

picklescan before 0.0.30 affected versions 0.0.26 and earlier fails to detect the ensurepip.runpip built-in function when scanning pickle files, allowing attackers to execute arbitrary code. Malicious pickle files embedding ensurepip.runpip calls in reduce methods bypass picklescan detection and...

CVE-2026-45034

Summary: PhpSpreadsheet before 1.30.5 contains a bypass in File::prohibitWrappers that can be exploited via phar:// wrapper paths (e.g., phar:///path/file.phar/inner). When input contains three or more slashes after the scheme, parse_url can return false, skipping the check and allowing phar wrap...

CVE-2026-45034 PhpSpreadsheet: File::prohibitWrappers bypass

PhpSpreadsheet is a pure PHP library for reading and writing spreadsheet files. Prior to 1.30.5, CVE-2026-34084 was patched by the helper File::prohibitWrappers. The helper calls parseurl$filename, PHPURLSCHEME and then checks isstring$scheme && strlen$scheme 1 to reject stream wrappers such as...

postgresql: integer overflow can cause an undersized allocation and an out-of-bounds write

A flaw was found in PostgreSQL. An integer overflow in multiple server features allows an unprivileged database user to cause an undersized memory allocation that leads to an out-of-bounds write. This issue allows an attacker to execute arbitrary code as the operating system user running the...

postgresql: PostgreSQL libpq: Buffer overflow allows server superuser to overwrite client stack memory

A flaw was found in PostgreSQL libpq. A server superuser can exploit a buffer overflow vulnerability in the PQfn function, which is used by client functions such as loexport, loread, lolseek64, and lotell64. This allows the superuser to send an arbitrarily large response, overwriting the client's...

CVE-2026-44727

Jupyter Server (prior to 2.20) is affected by a stored XSS in the nbconvert HTML export path. The nbconvert HTTP handlers NbconvertFileHandler and NbconvertPostHandler render notebook HTML under the Jupyter origin without a sandbox directive in Content-Security-Policy, and NbconvertHTMLExporter’s...
