A vulnerability in PostgreSQL JDBC Driver versions 42.7.4 through 42.7.11 allows silent downgrade of channel-binding authentication from SCRAM-SHA-256-PLUS to plain SCRAM-SHA-256. This downgrade removes the man-in-the-middle protection intended by channel binding when using certain certificate signature algorithms that lack a tls-server-end-point hash. The issue arises from a combination of a scram-client library returning empty binding data and pgJDBC not enforcing channel binding properly. The vulnerability is fixed in version 42.7.12. No workaround fully restores enforcement on affected versions; upgrading is required. Using strict TLS certificate verification (sslmode=verify-full) can mitigate the risk independently of channel binding.

In the Linux kernel, the following vulnerability has been resolved: scsi: target: iscsi: Validate CHAP_R length before base64 decode chap_server_compute_hash() allocates client_digest as kzalloc(chap->digest_size) and then, for BASE64-encoded responses, passes chap_r directly to chap_base64_decode() without checking whether the input length could produce more than digest_size bytes of output. chap_base64_decode() writes to the destination unconditionally as long as there is input to consume. With MAX_RESPONSE_LENGTH set to 128 and the "0b" prefix stripped by extract_param(), up to 127 base64 characters can reach the decoder. 127 characters decode to 95 bytes. For SHA-256 (digest_size=32) this overflows client_digest by 63 bytes; for MD5 (digest_size=16) the overflow is 79 bytes. The length check at line 344 fires after the write has already happened. The HEX branch in the same switch statement already validates the length up front. Apply the same approach to the BASE64 branch: strip trailing base64 padding characters, then reject any input whose data length exceeds DIV_ROUND_UP(digest_size * 4, 3) before calling the decoder. Stripping trailing '=' before the comparison handles both padded and unpadded encodings. chap_base64_decode() already returns early on '=', so the full original string is still passed to the decoder unchanged. The mutual CHAP path decodes CHAP_C into initiatorchg_binhex, which is kzalloc(CHAP_CHALLENGE_STR_LEN). extract_param() caps initiatorchg at CHAP_CHALLENGE_STR_LEN characters, so at most CHAP_CHALLENGE_STR_LEN-1 base64 characters reach the decoder. The maximum decoded size, DIV_ROUND_UP((CHAP_CHALLENGE_STR_LEN-1) * 3, 4), is less than CHAP_CHALLENGE_STR_LEN, so no overflow is possible there. A comment is added at the call site to document this.

A vulnerability in the Symfony PHP framework prior to versions 7.4.13 and 8.0.13 allows a signature algorithm downgrade in the MailomatRequestParser::validateSignature() function. This occurs because the function parses the X-MOM-Webhook-Signature header and passes the request-selected algorithm to hash_hmac() instead of enforcing the documented SHA-256 algorithm. The issue is fixed in Symfony versions 7.4.13 and 8.0.13.

Angular's HttpTransferCache used during Server-Side Rendering (SSR) employs a weak 32-bit hash for caching HTTP responses, leading to hash collisions. Attackers can craft requests that collide with sensitive endpoints, causing cached responses to be overwritten with attacker-controlled data. This results in state poisoning and potential information leakage. The vulnerability affects @angular/common versions up to 19.2.25 and has been fixed by switching to SHA-256 hashing in versions 20.3.25, 21.2.17, and 22.0.1. Workarounds include disabling transfer caching for sensitive requests or globally.

Microsoft released the Windows 10 KB5099539 extended security update, which includes the July 2026 Patch Tuesday fixes addressing 570 vulnerabilities, including two exploited and one publicly disclosed zero-day. This update is part of the extended security updates (ESU) program for Windows 10, now extended to October 12, 2027, for enrolled devices. It primarily contains security patches and bug fixes without new features, updating Windows 10 to build 19045.7548 and Windows 10 Enterprise LTSC 2021 to build 19044.7548. Notable fixes include resolving issues in OLE Automation, File Explorer, Recycle Bin, input hotkey behavior, Secure Boot status reporting, networking transport registration, and Remote Desktop security enhancements. Some legacy applications using unregistered TDI transports may stop working due to new security hardening. Microsoft recommends migrating to SHA-256 for RDP certificate thumbprints to avoid future disruptions.

ChurchCRM is an open-source church management system. Prior to version 7.4.0, an authenticated administrator can achieve Remote Code Execution (RCE) on the server by installing a malicious plugin ZIP archive containing a PHP webshell. The application explicitly includes 'php' in its ALLOWED_EXTENSIONS list, while the dangerous extensions denylist (DENIED_EXTENSIONS) fails to block standard .php files. Because `php` is explicitly included in the allowed extension list for plugin archives, and extracted files are placed directly under the web root, any PHP file inside the ZIP becomes immediately executable via HTTP — without even needing to "enable" the plugin through the application UI. The /plugins/install-url API route (management.php) allows an administrator to source the malicious ZIP from any attacker-controlled HTTPS URL, validating it only against an attacker-supplied SHA-256 hash. This issue has been fixed in version 7.4.0.

Part of the "Mini Shai-Hulud" supply chain worm campaign that compromised the GitHub Actions OIDC trusted publisher shared by Red Hat Cloud Services npm packages. The attacker injected a `preinstall` hook into this and 31 other packages in the `@redhat-cloud-services` scope. The hook delivers a three-layer obfuscated payload (ROT-9 Caesar cipher over a 1.27M-entry character-code array -> AES-128-GCM decryption with hardcoded keys -> stacked obfuscator.io encoding with PBKDF2+SHA-256 keystream S-box substitution) that downloads a pinned Bun runtime (v1.3.13) from GitHub to execute the worm outside the victim's Node installation. **Credential theft:** Harvests AWS credentials (IMDS, ECS, Secrets Manager, SSM), Azure managed identities, GCP service account tokens, HashiCorp Vault tokens, Kubernetes service account tokens (`/var/run/secrets/kubernetes.io/serviceaccount/token`), GitHub PATs, npm publish tokens, environment variables from ~40 CI platforms (CircleCI, Travis CI, Jenkins, and others), password manager stores (Bitwarden, gopass), and local files (`~/.npmrc`, `~/.netrc`, shell history, database history). Collected data is exfiltrated to attacker-controlled public GitHub repositories. **Privilege escalation:** Exploits Docker socket access to escape containers and modify `/etc/sudoers.d`, granting passwordless sudo to CI runner user accounts. **Self-propagation:** Uses stolen npm credentials to republish tampered tarballs of target packages. Injects a malicious CodeQL workflow into accessible GitHub repositories via the GraphQL `createCommitOnBranch` mutation, exchanges GitHub Actions OIDC tokens for npm publish tokens, and signs the resulting artifacts through Sigstore (Fulcio/Rekor) to appear legitimate. **Persistence and evasion:** Installs a daemon at `/tmp/kitty-<random>`, hijacks `.claude/settings.json` for AI agent persistence, and hijacks `.vscode/tasks.json` for editor task execution. Detects sandbox environments via `__FAKE_PLATFORM__`, `TESTING_TAR_FAKE_PLATFORM__`, and `__IS_DAEMON` environment variables, and probes for EDR tools (CrowdStrike, SentinelOne, Carbon Black, StepSecurity Harden-Runner). --- _-= Per source details.
