Home Assistant Core before 2026.6.0 contains a path traversal vulnerability that allows unauthenticated attackers to write arbitrary files to any directory on the host filesystem by uploading a crafted backup archive during the initial onboarding window. Attackers can manipulate the 'name' field inside the uploaded archive's backup.json to supply an absolute path, causing pathlib.Path.__truediv__ to discard the configured backup directory prefix and write attacker-controlled content to arbitrary locations, with full filesystem access when the process runs as root.

Jul 19, 2026In the Linux kernel, the following vulnerability has been resolved: sysfs: don't remove existing directory on update failure When sysfs_update_group() is callCVE-2026-64185 · Computers, phones & browsers · Linux · reported by 416baaa9-dc9f-4396-8d5f-8c081fb06d67Medium 5.5
In the Linux kernel, the following vulnerability has been resolved: sysfs: don't remove existing directory on update failure When sysfs_update_group() is called for a named group and create_files() fails (e.g. -ENOMEM), internal_create_group() calls kernfs_remove(kn) on the group directory. In the update path, kn was obtained via kernfs_find_and_get() and refers to a directory that already existed before this call. Removing it silently destroys a sysfs group that the caller did not create. Only remove the directory if we created it ourselves. On update failure the directory remains as it is left empty by remove_files() inside create_files(), but can be repopulated by a retry.

Jul 19, 2026In the Linux kernel, the following vulnerability has been resolved: thunderbolt: property: Cap recursion depth in __tb_property_parse_dir() A DIRECTORY entry'CVE-2026-63891 · Computers, phones & browsers · Linux · reported by 416baaa9-dc9f-4396-8d5f-8c081fb06d67
In the Linux kernel, the following vulnerability has been resolved: thunderbolt: property: Cap recursion depth in __tb_property_parse_dir() A DIRECTORY entry's value field is used as the dir_offset for a recursive call into __tb_property_parse_dir() with no depth counter. A crafted peer that chains DIRECTORY entries into a back-reference loop drives the parser until the kernel stack is exhausted and the guard page fires. Any untrusted XDomain peer (cable, dock, in-line inspector, adjacent host) that reaches the PROPERTIES_REQUEST control-plane exchange can trigger this without authentication. Thread a depth counter through tb_property_parse() and __tb_property_parse_dir(), and reject blocks that exceed TB_PROPERTY_MAX_DEPTH = 8. That is comfortably larger than any observed legitimate XDomain layout. Operators who do not need XDomain host-to-host discovery can disable the path entirely with thunderbolt.xdomain=0 on the kernel command line.

@hapi/inert provides static file and directory handlers for hapi.js. From 4.0.0 to 7.1.0, @hapi/inert serves static files from a directory configured with path in the directory or file handlers or relativeTo for h.file(), with confinement enforced by the confine option, but the confinement check compared the resolved absolute path against the confine directory using a raw string-prefix test, so a sibling directory such as /app/static-secret next to /app/static was incorrectly accepted and could allow an unauthenticated remote attacker to read files via /..%2fstatic-secret/secret.txt. This issue is fixed in version 7.1.1.

File Browser is a file managing interface for uploading, deleting, previewing, renaming, and editing files within a specified directory. From 2.63.6 to 2.63.16, File Browser's archive builder uses strings.ReplaceAll(nameInArchive, "\", "/"), which turns a POSIX filename such as ..\..\evil.sh into the archive entry ../../evil.sh, allowing a user with upload permission to plant a backslash-named file that escapes the extraction directory when another user downloads and extracts the generated zip or tar archive. This issue is fixed in version 2.63.17.

File Browser is a file managing interface for uploading, deleting, previewing, renaming, and editing files within a specified directory. Prior to 2.63.17, File Browser builds new user scopes from usernames passed through cleanUsername() when Signup=true and CreateUserDir=true, but the many-to-one normalization can collapse usernames such as team/one, team one, and team-one to the same home directory without checking whether the resulting scope is already taken, allowing a second registrant to gain full read and write access to another user's files.

File Browser is a file managing interface for uploading, deleting, previewing, renaming, and editing files within a specified directory. Prior to 2.63.17, File Browser can leave a public directory share behind when the shared directory is deleted through a path with a trailing slash because the share cleanup path calls DeleteWithPathPrefix(file.Path, userID) and the Bolt backend performs the database prefix query with the unnormalized path before trimming the slash for boundary checks, so deleting /a/ does not delete the stored /a share and the stale public share exposes future content if the same path is recreated. This issue is fixed in version 2.63.17.

The NGINX Agent config_dirs directive allows a low-privileged attacker to gain limited read and write access to files outside of the designated secure directory. The config_dirs directive required for this issue can also be configured through NGINX Instance Manager. A successful exploit may allow an attacker to cross a security boundary. Impact: A remotely authenticated low-privileged attacker could gain limited read and write access outside of the list of directories specified in the NGINX Agent configuration.

Cornac before 2.6.0 contains a path traversal (Tar Slip) vulnerability that allows attackers to write arbitrary files outside the intended cache directory by supplying a crafted TAR archive containing ../ sequences, absolute paths, or symlink/hardlink entries to the _extract_archive() function in cornac/utils/download.py.

Where this comes from: the exploited list is CISA’s Known Exploited Vulnerabilities catalog. Everything else is the whole National Vulnerability Database, where each record is published by the team that found the bug (Wordfence, Patchstack, WPScan, the vendors themselves and others); we show who. Exploit odds are FIRST’s EPSS, updated daily. Titles and categories are ours, so check the linked record before acting on a detail. For a write-up of the big ones, see our advisories. Every vendor, and every WordPress plugin and theme with a recorded flaw, also has its own page. All of it is free to reuse as JSON, CSV or RSS.
