kernel: XFS data corruption using reflink

A flaw was found in the XFS filesystem. A race condition in the copy-on-write mechanism for reflinked files can cause writes to bypass the copy-on-write process and modify shared data blocks directly. As a result, data intended for a private copy may be written to the original shared location,...

EUVD-2026-43577

Cockpit CMS contains a path traversal vulnerability in the Bucket file storage API /system/buckets/api. The api method in modules/System/Controller/Buckets.php sanitizes the bucket name with pregreplace'/^a-zA-Z0-9-\./','', $bucket, which permits '..' and '../' sequences. The sanitized value is...

Fortinet Fortigate Path traversal in CLI command allows deletion of root file system (FG-IR-26-151)

The version of Fortigate installed on the remote host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the FG-IR-26-151 advisory. - A improper limitation of a pathname to a restricted directory 'path traversal' vulnerability in Fortinet FortiOS 7.6.0...

PYSEC-2026-2539 jupyterlab-git excluded_paths Case-Sensitivity Bypass Allows Reading Excluded Directories

Summary jupyterlab-git 0.53.0 latest, 2026-04-30 uses fnmatch.fnmatchcase in GitHandler.prepare jupyterlabgit/handlers.py:91 to enforce the admin-configured excludedpaths security control. Because fnmatchcase is unconditionally case-sensitive, an authenticated user on a case-insensitive filesyste...

PYSEC-2026-2566 Langflow: Path Traversal in Knowledge Bases API via Creation Endpoint

Summary Langflow is vulnerable to Path Traversal in the Knowledge Bases API POST /api/v1/knowledgebases. This occurs because user-supplied knowledge base names are used directly to create file paths without proper sanitization or containment checks. An authenticated attacker can exploit this flaw...

PYSEC-2026-3428 WsgiDAV encoded dot segments can escape filesystem share roots

Impact WsgiDAV 4.3.3 can allow a WebDAV request path containing an encoded parent-directory segment to escape the configured filesystem share root in a specific path layout. Patches The issue is fixed with version 4.3.4. Preconditions The practical impact depends on the deployment. The deployment...

PYSEC-2026-2861 PDM wheel installation leads to Path Traversal via overridden write_to_fs

InstallDestination.writetofs in src/pdm/installers/installers.py overrides the base class to add symlink/hardlink support but replaces the safe pathwithdestdir which validates via Path.resolve + isrelativeto with a bare os.path.join that performs no path validation. A malicious wheel with travers...

CVE-2026-15584

The CVE-2026-15584 issue concerns the incluster-checks tool in OpenShift. It describes a privilege-escalation flaw where the tool creates privileged debug pods with host filesystem access in the shared default namespace. Any user possessing the standard edit role can execute into these pods and o...

CVE-2026-15584

A privilege escalation vulnerability was found in the incluster-checks tool for OpenShift. The tool creates privileged debug pods with host filesystem access in the shared default namespace, where any user with the standard edit role can exec into them and obtain root access on cluster nodes...

[SECURITY] Fedora 43 Update: attr-2.6.0-1.fc43

A set of tools for manipulating extended attributes on filesystem objects, in particular getfattr1 and setfattr1. An attr1 command is also provided which is largely compatible with the SGI IRIX tool of the same name...

The functions xfs reflink fill cow hole and xfs reflink fill delalloc cycle the ILOCK to acquire a transaction...

PT-2026-59213

Summary Several LangChain components that resolve filesystem paths or expand search patterns do not consistently confine the resolved path to the intended root directory. Affected behaviors include: a file-search agent middleware that validates a starting directory but not the search pattern or t...

CVE-2026-47261

A flaw was found in Wasmtime, a runtime for WebAssembly. This vulnerability allows an attacker to bypass intended access controls when a filesystem preopen is configured with read-only file permissions but also allows directory mutations. By using specific open flags, an attacker can truncate fil...

CVE-2026-55781

The CVE affects NanaZip (7-Zip derivative) prior to version 6.5.1749.0, specifically the UFS/FFS image handler in NanaZip.Codecs.Archive.Ufs.cpp. The root cause is that superblock considerations validate the block size only against MINBSIZE and do not validate the fs_fsize fragment size, allowing...

USN-8530-1 linux-aws, linux-aws-fips vulnerabilities

It was discovered that the Linux kernel did not properly handle shared page fragments during socket buffer operations, collectively known as Dirty Frag. A logic flaw existed in the XFRM ESP-in-TCP subsystem and in the RxRPC networking subsystem when processing paged fragments. A local attacker...

CVE-2026-54528

A flaw was found in JupyterLab Git, a Git extension for JupyterLab. This vulnerability allows an authenticated user on a case-insensitive filesystem to bypass administrator-configured excluded paths by varying the case of the URL path segment. This bypass enables the user to read file content, vi...

decompress: Decompress: File disclosure and corruption via arbitrary hardlink creation

A flaw was found in decompress. An attacker can craft a malicious archive that, when extracted, allows for arbitrary hardlink creation. This vulnerability occurs because the x.linkname field from hardlink entries in the archive is processed without proper validation, enabling an attacker to creat...

EUVD-2026-42768

decompress before 4.2.2 allows arbitrary hardlink creation during archive extraction, enabling file read disclosure and file corruption. When processing hardlink entries type === 'link', the x.linkname field from the archive is passed directly to fs.link without validation index.js line 113. An...
