CVE-2026-27878

Tempo TraceQL query with exemplar hint could result in unbounded memory usage

A TraceQL query in Grafana Tempo with a large exemplars hint value can cause the Tempo instance to allocate an excessive amount of memory, resulting in an out-of-memory crash. This could allow an authenticated user to trigger a denial of service against the Tempo service.

CVE-2026-49337

libde265 has an unbounded memory leak via orphaned slice headers in `read_slice_NAL`

libde265 is an open source implementation of the h.265 video codec. Prior to version 1.0.20, a crafted sequence of H.265 NAL units causes `decoder_context::read_slice_NAL()` (`libde265/decctx.cc:481`) to attach slice headers to a finished picture object that has no active image unit, resulting in attacker-controlled unbounded heap growth. The retained headers are never freed until the picture is released, which may not happen during continuous streaming. Version 1.0.20 patches the issue.

CVE-2026-49295

libde265 has an out-of-bounds write in process_reference_picture_set via predicted short-term RPS

libde265 is an open source implementation of the h.265 video codec. Prior to version 1.0.20, a crafted H.265 bitstream can cause an out-of-bounds array write in `decoder_context::process_reference_picture_set()` (`libde265/decctx.cc:1376`). The root cause is a missing aggregate bound check on predicted short-term reference picture set entries. Individual list sizes are validated, but the combined count after predicted RPS construction can exceed the 16-entry `PocStFoll` array, writing at index 16. Version 1.0.20 patches the issue.

CVE-2026-49346

libde265 has a heap buffer overflow in de265_image_get_buffer via SPS dimension integer overflow

libde265 is an open source implementation of the h.265 video codec. Prior to version 1.1.0, a crafted H.265 bitstream with large SPS dimensions and 16-bit bit depth causes a signed integer overflow in `de265_image_get_buffer()` (`libde265/image.cc:128`). The overflow wraps the plane allocation size to a small value (~1 KB), but the subsequent `fill_image()` call computes the real size using `size_t`, writing ~4 GB into the undersized heap buffer. Version 1.1.0 patches the issue.

Cap-go - Authentication Logic Flaw in Enforce Password Policy

Capgo before 12.128.2 contains a flaw in the Enforce Password Policy feature: after a Super Admin enables the policy and successfully changes their password to a compliant one, the backend does not update the password-compliance state. As a result, the backend continues to treat the account as non-compliant and repeatedly forces password-reset prompts, permanently locking the Super Admin out of organization access (organization lockout / denial of service) despite valid authentication.

Cap-go - Account Lockout via 2FA Misconfiguration on Unverified Email

Cap-go before 12.128.2 contains an authentication logic flaw that lets an attacker register and control an account bound to a victim's email address before that email is verified. By enabling two-factor authentication on the pre-registered account, the attacker gains control over the account claimed under the victim's identity, allowing them to read and modify its state and enforce organization-level policies, while the legitimate user is denied access to the account tied to their own email.

Capgo - Unauthenticated Cross-Tenant Billing Log Tampering via public.record_build_time RPC

Capgo (Cap-go/capgo) before 12.128.2 contains an improper access control vulnerability in the SECURITY DEFINER PostgREST RPC function public.record_build_time, which is granted to the anon role and callable with only the public Supabase publishable (sb_publishable_*) anon key. An unauthenticated attacker can insert rows into public.build_logs for arbitrary organizations and, because the function uses ON CONFLICT (build_id, org_id) DO UPDATE, can overwrite existing usage/billing records by reusing the same build_id for a target org. This enables cross-tenant tampering of billing build logs and financial-impact denial of service by inflating billable build time.

Branda – White Label & Branding, Free Login Page Customizer <= 3.4.29 - Unauthenticated Privilege Escalation via Account Takeover

The Branda plugin for WordPress is vulnerable to privilege escalation via account takeover in all versions up to, and including, 3.4.29. This is due to the plugin not properly validating a user's identity prior to updating their password. This makes it possible for unauthenticated attackers to change arbitrary user's passwords, including administrators, and leverage that to gain access to their account.

Capgo - Improper 2FA Enforcement Logic via Team Security Settings

Capgo before 12.128.2 contains an authentication logic flaw: a user with permission to manage team or organization security settings can enable mandatory two-factor authentication for all team members without first enabling 2FA on their own account. The application fails to verify the initiator's 2FA status before allowing the policy change, resulting in inconsistent security enforcement, potential administrative misuse, and lockout risk for team members.
