PT-2026-56502

Name of the Vulnerable Software and Affected Versions linkify-it versions prior to 5.0.2 Description The mailto: schema validator used by the .test and .match functions can be triggered at every occurrence of mailto: and scan the remaining input via src email name in lib/re.mjs. This behavior lea...

CVE-2026-53751

DataEase is an open source data visualization and analysis tool. Prior to 2.10.24, the H2 database JDBC URL validation logic can be bypassed with special Unicode characters whose case-conversion behavior differs between DataEase validation and H2 parsing, allowing attackers to smuggle dangerous...

CVE-2026-53751

CVE-2026-53751 affects DataEase prior to 2.10.24. The vulnerability arises from the H2 database JDBC URL validation being bypassable by Unicode characters whose case-conversion behavior differs between DataEase’s validation and H2 parsing, enabling an attacker to smuggle dangerous parameters (e.g...

PYSEC-2026-1109 AIOHTTP has unicode match groups in regexes for ASCII protocol elements

Summary The parser allows non-ASCII decimals to be present in the Range header. Impact There is no known impact, but there is the possibility that there's a method to exploit a request smuggling vulnerability. ---- Patch:...

PYSEC-2026-1099 AIOHTTP's unicode processing of header values could cause parsing discrepancies

Summary The Python HTTP parser may allow a request smuggling attack with the presence of non-ASCII characters. Impact If a pure Python version of aiohttp is installed i.e. without the usual C extensions or AIOHTTPNOEXTENSIONS is enabled, then an attacker may be able to execute a request smuggling...

JLSEC-2026-655 Deno: Permission Bypass via Unicode Normalization Mismatch on macOS (APFS)

Summary Deno's permission system enforces filesystem and execution restrictions by comparing the requested path against the path supplied to --deny-read, --deny-write, --deny-run, or --deny-ffi. On macOS, that comparison was done at the raw-byte level while the APFS filesystem treats different...

PYSEC-2026-1455 Arbitrary HTML present after sanitization because of unicode normalization

Impact If using keeptypographicwhitespace=False which is the default, the sanitizer normalizes unicode to the NFKC form at the end. Some unicode characters normalize to chevrons; this allows specially crafted HTML to escape sanitization. Patches The problem has been fixed in 2.4.2. Workarounds Se...

golang.org/x/net/idna: golang: net/http: golang.org/x/net/idna: Privilege escalation via incorrect Punycode label processing

A flaw was found in golang.org/x/net/idna. ToASCII and ToUnicode incorrectly accept Punycode-encoded labels that decode to an ASCII-only hostname for example, xn--example-.com returns example.com instead of an error. Applications that validate the ASCII form then convert to Unicode may grant acce...

Issue Overview: Parsing arbitrary HTML can consume excessive CPU time, possibly leading to denial of service. CVE-2026-25680 Parsing arbitrary HTML which is then rendered using Render can result in an unexpected HTML tree. This can be leveraged to execute XSS attacks in applications that attempt ...

Important: python3.13

Issue Overview: tarfile.extractall with the 'data' or 'tar' filter could be bypassed by a crafted archive where a hardlink references a symlink stored at a deeper name than the hardlink itself. The extraction fallback validated the symlink at it's archived location but recreated it at the...

GHSA-6GCW-W7CP-94G9 comm: lossy UTF-8 conversion silently corrupts non-UTF-8 output

The comm utility in uutils coreutils silently corrupts data by performing lossy UTF-8 conversion on all output lines. The implementation uses String::fromutf8lossy, which replaces invalid UTF-8 byte sequences with the Unicode replacement character U+FFFD. This behavior differs from GNU comm, whic...
