🔐 Passkeys replace passwords with public-key cryptography, keeping the private key on the user’s device while services retain only a public key. They prevent phishing, credential stuffing, and brute-force attacks, and are unlocked by local authentication such as biometrics or a PIN. FIDO research and high-profile moves by Microsoft and Aflac highlight improved convenience and reduced support costs, but device dependency, legacy compatibility, and implementation costs remain significant challenges.

🔒 Rapid7 disclosed an unpatched vulnerability in OnePlus's OxygenOS (CVE-2025-10184) that allows any installed app to access SMS content and metadata without SMS permissions. The fault arises from modified Telephony content providers whose manifests omit a required write permission and accept unsanitized input. By abusing a blind SQL-injection vector an attacker can infer SMS text one character at a time. OnePlus has acknowledged the report and is investigating; users should minimize installed apps and avoid SMS-based 2FA.

⚠️ Trend Micro disclosed two critical authentication-bypass vulnerabilities in Wondershare RepairIt that exposed private user files, AI models, and build artifacts due to embedded overly permissive cloud tokens and unencrypted storage. The flaws, tracked as CVE-2025-10643 (CVSS 9.1) and CVE-2025-10644 (CVSS 9.4), allow attackers to circumvent authentication and potentially execute arbitrary code via supply-chain tampering. Trend Micro reported the issues through ZDI in April 2025 and warns users to restrict interaction with the product until a vendor fix is issued.

🔒 Researchers disclosed two critical vulnerabilities in Lovense remote-control software that exposed real user email addresses and allowed attackers to generate authentication tokens using only an email, without passwords. Combined, these flaws enabled account takeover across multiple products including Lovense Remote, Lovense Connect and streaming extensions. Reported in spring 2025, fixes were delayed and fully applied only after public disclosure; users should consider separate emails and strong, unique passwords.

🔒 Cybersecurity researchers disclosed two medium-severity vulnerabilities in Supermicro Baseboard Management Controller (BMC) firmware that allow crafted images to bypass signature verification and install malicious firmware. The issues, tracked as CVE-2025-7937 (CVSS 6.6) and CVE-2025-6198 (CVSS 6.4), exploit manipulation of embedded validation tables — fwmap and sig_table — to trick the verification logic into accepting unsigned regions. Binarly reported the findings, detailed how the auth_bmc_sig flow on an X13SEM-F board can be subverted, and recommends rotating signing keys, hardening validation logic, and applying vendor firmware updates promptly.

🔒 Microsoft has patched a critical token validation failure in Entra ID (formerly Azure AD), tracked as CVE-2025-55241 and assigned a CVSS score of 10.0. The flaw combined misused service-to-service (S2S) actor tokens issued by the Access Control Service (ACS) with a validation gap in the legacy Azure AD Graph API that enabled cross-tenant impersonation, including Global Administrators. Microsoft released a fix on July 17, 2025 and said no customer action is required; there is no indication the issue was exploited in the wild. Security firms warned the vulnerability could bypass MFA, Conditional Access and logging, potentially enabling full tenant compromise.

🔒 A critical token validation flaw in Microsoft Entra ID could permit full tenant compromise by abusing undocumented, unsigned actor tokens issued by a legacy Access Control Service. Researcher Dirk-jan Mollema showed that when paired with a vulnerability in the deprecated Azure AD Graph API (CVE-2025-55241) those tokens could impersonate any user — including Global Administrators — across tenants without leaving tenant logs. Microsoft confirmed a fix after the July report and later patched the CVE.

⚠️ Westermo disclosed an OS command injection vulnerability in WeOS 5 (CVE-2025-46418) affecting versions 5.24 and later.
