Your PHP site can be broken by a request carrying no credentials, even when every page demands a login. The flaw sits in how PHP handles a request, not in your code: exiting on memory exhaustion leaves half-initialised request data behind, and state carried across requests can point at memory already freed. Both fire before your code runs; exploitation is demonstrated against Apache mod_php.

PwnEscape: how a VM's outgoing packets exposed host memoryThe host finishes a VM's checksum but writes the result into an IPv4 header it has already checked. Fragmentation then trusts the altered header length. In the researchers' example, it copies 32 extra bytes, sending host memory out with the packet. Fixing CVE-2026-99999 requires updating the host kernel. Updating only the system inside the VM leaves this code unchanged.

AdFection: how ads delivered spyware without a clickAn ad can run code as soon as it loads. New investigations by Citizen Lab and Confiant connect ad buying, selective delivery and spyware infections. Some ads also collected publishers' own login sessions. The useful defense question is what authority an ad receives, beyond whether a user clicks it.

The Filter That Kept Its Account ID and Still Reached Beyond the TenantChatwoot 2.2.0 through releases before 4.11.2 are affected by CVE-2026-44706 because authenticated filter values and stored custom-attribute keys gained PostgreSQL syntax in FilterService; deploy current official 4.16.1 to web and workers, inventory legacy keys and export jobs, and close after synthetic two-account tests pass under the real database role, with 4.11.2 kept only as the historical first-fixed floor.

7-Zip NTFS Parser One-Byte Buffer (CVE-2026-48095)CVE-2026-48095 joins an oversized NTFS cluster exponent to a compressed-attribute value inside 7-Zip, so a 32-bit shift collapses the input allocation to one byte in the tested builds before one extent can supply 256 MiB; every parser copy through 26.00 should move to the current official 26.02, or at minimum 26.01 or a backport verified against the same source invariant.

The Empty Request That Erased Two Routes — Reconstructing Tailscale TS-2026-002TS-2026-002 allowed an authenticated tailnet peer that could reach an explicitly exposed device web interface on TCP 5252 to send a route request selecting no operation; the old handler asked for neither route capability, preserved neither existing route group, and then gave two empty values explicit write authority, clearing the target's active exit node and advertised subnet routes.

The Semicolon That Walked Past Quarkus Authorization (CVE-2026-39852)Quarkus HTTP security once matched permissions against a path carrying matrix parameters while RESTEasy dispatched the same resource by its base path; production should run a supported maintenance release with the June full-normalization repair and accept it with policy, destination, side-effect, and running-artifact evidence.
