🚨 CVE-2026-23697
Vtiger CRM before 8.4.0 contains an authenticated file upload vulnerability that allows low-privileged users to achieve remote code execution by uploading a .phar file containing arbitrary PHP code through the Documents module, bypassing the extension denylist in config.inc.php which omits the .phar extension. The uploaded file is stored with its original .phar extension under the web-accessible storage directory, and a misconfigured .htaccess using Apache 2.2 syntax is silently ignored on Apache 2.4 deployments, allowing unauthenticated HTTP requests to directly execute the uploaded PHP payload.

🚨 CVE-2026-55435
Coder allows organizations to provision remote development environments via Terraform. Starting in version 2.30.0 and prior to versions 2.32.7, 2.33.8, and 2.34.2, AI Bridge proxy endpoints authenticate via `Server.IsAuthorized` in `coderd/aibridgedserver`, which validates key format, expiry, secret and deleted or system users but does not check whether the account is suspended. Because suspension does not revoke existing API keys, a suspended user's unexpired token keeps working. Practical impact is limited to already-issued API keys of suspended users until those keys are deleted. Versions 2.32.7, 2.33.8, and 2.34.2 patch the issue. As a workaround, on suspension, delete the user's API keys via `DELETE /api/v2/users/{user}/keys`.

🚨 CVE-2026-59800
9Router before 0.4.44 contains an OS command injection vulnerability in the unauthenticated POST /api/tunnel/tailscale-install endpoint (this route is not covered by the dashboard middleware matcher, so no authorization check is applied). The sudoPassword field from the request body is written to the stdin of a 'sudo -S sh' child process. When sudo does not prompt for a password (the process runs as root, NOPASSWD is configured, or a recent sudo timestamp cache exists), the sudoPassword value is interpreted by sh as a shell command, allowing a remote unauthenticated attacker to execute arbitrary OS commands. Exploitation evidence was first observed by the Shadowserver Foundation on 2026-07-04 (UTC).

🚨 CVE-2026-7017
HTTP::Tiny versions before 0.095 for Perl forward credential headers to cross-origin redirect targets.

When the server returns a 3xx redirect, `_maybe_redirect` follows the `Location:` header and `_prepare_headers_and_cb` re-merges the caller's `headers` argument into the new request, without checking whether the redirect target shares an origin with the original URL. Caller-supplied `Authorization`, `Cookie` and `Proxy-Authorization` headers are therefore re-sent to whatever host the redirect names, across scheme, host or port boundaries, and including `https` to `http` downgrades that expose them in plaintext on the wire.

The HTTP::Tiny POD note that "Authorization headers will not be included in a redirected request" applied only to the URL-userinfo Basic-auth path, not to headers passed explicitly by the caller.

🚨 CVE-2026-12064
When a user invokes curl using a schemeless URL combined with
`--proto-default` sftp (or scp), a disconnect occurs between the tool layer
and libcurl. The tool layer incorrectly infers the URL scheme, which
erroneously bypasses the initialization of critical SSH security options like
CURLOPT_SSH_HOST_PUBLIC_KEY_SHA256 and CURLOPT_SSH_KNOWNHOSTS. Conversely, the
libcurl runtime successfully honors CURLOPT_DEFAULT_PROTOCOL and establishes
the connection via SFTP/SCP as specified. Because the tool layer skipped the
security configuration, these SSH host verification options are silently
omitted, causing curl to connect to an unverified SSH remote host without
throwing an error.

🚨 CVE-2026-53154
In the Linux kernel, the following vulnerability has been resolved:

mm/hugetlb: restore reservation on error in hugetlb folio copy paths

Two sites in mm/hugetlb.c allocate a hugetlb folio via
alloc_hugetlb_folio() (consuming a VMA reservation) and then call
copy_user_large_folio(), which became int-returning in commit 1cb9dc4b475c
("mm: hwpoison: support recovery from HugePage copy-on-write faults") and
can now fail (e.g. -EHWPOISON on a hwpoisoned source page). On the
failure path, folio_put() restores the global hugetlb pool count through
free_huge_folio(), but the per-VMA reservation map entry is left marked
consumed:

- hugetlb_mfill_atomic_pte() resubmission path (UFFDIO_COPY)
- copy_hugetlb_page_range() fork-time CoW path when
hugetlb_try_dup_anon_rmap() fails (rare: pinned hugetlb anon
folio under fork)

User-visible effect: on UFFDIO_COPY into a private hugetlb VMA where the
resubmission copy fails, the reservation for that address is leaked from
the VMA's reserve map. A subsequent fault at the same address takes the
no-reservation path, and under hugetlb pool pressure the task is SIGBUSed
at an address it had previously reserved. The fork-time CoW path leaks
the same way in the child VMA's reserve map, though it requires the much
rarer combination of pinned hugetlb anon page + hwpoisoned source.

Add the missing restore_reserve_on_error() call before folio_put() on both
error paths.

🚨 CVE-2026-53155
In the Linux kernel, the following vulnerability has been resolved:

mm/huge_memory: use correct flags for device private PMD entry

Commit 65edfda6f3f2 ("mm/rmap: extend rmap and migration support
device-private entries") updated set_pmd_migration_entry() to use
pmdp_huge_get_and_clear() in the softleaf case, but made no further
adjustments to the function itself.

Therefore this function continues to incorrectly use pmd_write(),
pmd_soft_dirty() and pmd_uffd_wp() to determine whether the installed
migration entry should be marked writable, softdirty or uffd-wp
respectively.

Whilst all are incorrect, the most problematic of these is pmd_write(), as
this can lead to corrupted rmap state.

On x86-64 _PAGE_SWP_SOFT_DIRTY is aliased to _PAGE_RW. So calling
pmd_write() on a softleaf will return the softdirty state encoded in the
entry, assuming CONFIG_MEM_SOFT_DIRTY was enabled.

This was observed when running the hmm.hmm_device_private.anon_write_child
selftest:

1. The test faults in a range then migrates it such that a device-private
THP range is established.

2. The parent then migrates it to a device-private writable PMD entry whose
folio is entirely AnonExclusive with entire_mapcount=1, softdirty set
(accidentally correct write state).

3. The parent forks and the PMD entries are set to device-private read only
entries, entire_mapcount=2, softdirty still set.

4. [BUG] The child writes to the range then migrates to RAM - intending to
install non-writable migration entries - but replacing parent and child
PMD mappings with WRITABLE entries due to misinterpreting the softdirty
bit.

5. In remove_migration_pmd(), if !softleaf_is_migration_read(entry) we
set the RMAP_EXCLUSIVE flag when calling folio_add_anon_rmap_pmd() for
both parent and child, which are therefore AnonExclusive.

6. [SPLAT] Child sets migrated folio entire_mapcount=1, parent sets
entire_mapcount=2 and we end up with an AnonExclusive folio with
entire_mapcount=2! Assert fires in __folio_add_anon_rmap():

VM_WARN_ON_FOLIO(folio_test_large(folio) &&
folio_entire_mapcount(folio) > 1 &&
PageAnonExclusive(cur_page), folio)

This patch fixes the issue by correctly referencing the softleaf entry
fields for writable, softdirty and uffd-wp in set_pmd_migration_entry().

It also only updates A/D flags if the entry is present as these are
otherwise not meaningful for a softleaf entry.

This patch also flips the if (!present) { ... } else { ... } logic in
set_pmd_migration_entry() so it is easier to understand, and adds some
comments to make things clearer.

I was able to bisect this to commit 775465fd26a3 ("lib/test_hmm: add zone
device private THP test infrastructure") which first exposes this bug as
it was the commit that permitted test_hmm to generate the test.

However commit 65edfda6f3f2 ("mm/rmap: extend rmap and migration support
device-private entries") is the commit that actually enabled this
behaviour.
