Unpatched Kaltura mwEmbed Flaws Could Let Remote Attackers Read Files and Run Code
CERT/CC disclosed unpatched Kaltura mwEmbed flaws CVE-2026-19913 and CVE-2026-19912 allowing unauthenticated file reads and remote code execution.
CERT/CC disclosed two unpatched flaws in Kaltura's mwEmbed HTML5 player library, both rooted in unsafe deserialization in mwEmbedLoader.php and exploitable without authentication. CVE-2026-19913 (reporter-scored 9.1) reflects local file contents back via the ServiceUrl parameter, exposing secrets in local.ini; CVE-2026-19912 (reporter-scored 10.0) achieves PHP code execution by writing attacker-controlled objects into web-accessible directories via the uiconf_id parameter. No patch exists and CERT/CC could not reach Kaltura; affected releases include html5lib v2.45, v2.103 and earlier, with the shared multi-tenant CDN hosts also impacted. No exploitation or KEV listing was reported as of August 25, 2026.
Skullcandy Dime 3 earbuds expose users to Bluetooth hijacking
CERT/CC warns Skullcandy Dime 3 earbuds accept silent Bluetooth pairings via CVE-2025-20701, letting nearby attackers hijack audio and microphone.
CERT/CC reports the Skullcandy Dime 3 (model S2DCW) running firmware 1.0.0.28 is affected by CVE-2025-20701, a high-severity missing-authentication flaw in the Airoha Bluetooth Audio SDK. An attacker in close range can pair without user interaction, then hijack audio playback, access the headset profile, and capture live microphone audio. Skullcandy fixed the issue in firmware 1.0.0.30, but existing units have no consumer-accessible update path via the app. The flaw was discovered by ERNW researchers and affects earbud and headphone products from multiple vendors; Apple patched it for Beats Studio Buds in June.
VU#369611: ExLlamaV3 contains Denial of Service vulnerability via insufficient bounds checking on kernel dispatch index
CERT/CC details CVE-2026-84286, an out-of-bounds memory access in ExLlamaV3's CUDA extension causing denial-of-service crashes; fixed via merged pull request.
CERT/CC published VU#369611 for CVE-2026-84286, an out-of-bounds memory access in the exllamav3_ext CUDA extension of the ExLlamaV3 LLM inference library. A crafted input with kernel parameter K set to 0 produces a negative index into a fixed 24-entry kernel dispatch array, causing a CUDA illegal memory access and denial-of-service crashes. The vendor fixed the issue in the main repository via pull request #310, and maintainers of 49 downstream projects, including ezexl3 and MawDiscord, are advised to rebuild against the patched version. The issue was reported by Nathan Keys and impact is limited to crashes and instability, not code execution.
VU#718077: UEFI Shell module embedded in SPI Flash can be used to bypass Secure Boot
CERT/CC details VU#718077: UEFI Shell embedded in SPI flash lets attackers bypass Secure Boot and execute pre-boot code; patches issued.
CERT/CC's VU#718077, reported by Eclypsium researcher Stas Lyakhov, describes how a UEFI Shell embedded in SPI flash can be abused by attackers who can modify UEFI boot configuration, creating multiple boot entries that bypass controls preventing the Shell from launching under Secure Boot. The Shell's dmem and mm commands allow arbitrary physical memory read/write, letting attackers overwrite Secure Boot values and execute unauthorized pre-boot code that can persist across reboots and OS reinstalls while degrading EDR effectiveness. AMI confirmed its Aptio UEFI BDS module is affected (CVE-2026-33197), and Cisco published an advisory for a variation affecting UCS Servers and UCS-based appliances (CVE-2026-20293). Firmware patches are being rolled out through OEM and IBV BIOS build pipelines.
VU#728712: Konami's Metal Gear Online 3 contains a heap-based buffer overflow
CERT/CC details CVE-2026-19874, a heap overflow in Metal Gear Online 3 letting match hosts execute code on lobby members' machines.
VU#728712 describes a heap-based buffer overflow in Konami's Metal Gear Online 3, tracked as CVE-2026-19874, affecting version 1.1.2.8 (Steam AppID 287700). The input-validation flaw lies in processing Steam lobby metadata tied to the player-removal feature, letting a match host trigger remote code execution on lobby members' machines via specially crafted data. The game is an 8v8 competitive shooter using Steam Matchmaking for lobbies.
VU#756733: Calix GS7 XGS GS5239XG residential router contains missing authentication vulnerability
CERT/CC warns Calix GS7 XGS GS5239XG routers on firmware EXOS/6.6.47 expose an unauthenticated UPnP WANIPConnection service on the public WAN interface.
CERT/CC issued VU#756733 for a missing authentication vulnerability in the Calix GS7 XGS GS5239XG residential gateway running EXOS/6.6.47. The device's UPnP service, implemented with MiniUPnPd 2.3.7, is exposed on the WAN interface by default and does not require authentication, potentially letting remote attackers alter port mappings through the WANIPConnection service. The flaw affects routing, NAT, and firewall functionality for home networks.
VU#874418: RDK-B WebUI contains multiple vulnerabilities
CERT/CC warns RDK-B WebUI rdkb-2025q4-kirkstone contains multiple flaws enabling network attackers to bypass authentication, cause DoS, or potentially execute code.
VU#874418 describes multiple vulnerabilities in the RDK-B WebUI version rdkb-2025q4-kirkstone, the open-source Reference Design Kit for Broadband used in broadband gateways and networking devices. Issues include memory corruption, improper authentication, race conditions, and insufficient input validation. A network-adjacent attacker could bypass authentication, obtain administrative access, cause denial-of-service, or corrupt underlying processes, with potential arbitrary code execution under certain conditions.
VU#431093: TCG TPM 2.0 reference code found vulnerable to information leakage and timing side-channel attacks
CERT/CC discloses two TPM 2.0 reference code flaws allowing RSA key decryption and forged TPM attestations via crafted commands.
CERT/CC published VU#431093 covering two vulnerabilities in the TCG TPM 2.0 reference implementation: CVE-2026-6726 (information leakage via falsified TPM keys) and CVE-2026-6727 (timing side-channel in RSA OAEP decryption). An attacker with privileged access to a TPM command interface could send crafted TPM commands to decrypt ciphertexts for affected TPM-managed RSA keys, including the RSA Endorsement Key, or obtain credentials enabling forged TPM 2.0 attestations. Remediation is tracked in TCGVRT010 and TCGVRT0011.
