Welcome to today's edition of Secret CISO, where we unravel the tangled web of cybersecurity incidents and vulnerabilities that are shaping the digital landscape. In this issue, we delve into a series of alarming data breaches that have rocked major corporations and institutions, underscoring the persistent risks of third-party data handling and the urgent need for robust security measures.

Comcast faces a hefty $1.5 million fine after a vendor's data breach exposed the personal information of 237,000 customers, while SitusAMC's breach has compromised data from over 100 financial institutions, highlighting vulnerabilities in the banking sector. Meanwhile, DoorDash is embroiled in a class-action lawsuit over a breach that threatens user identities, and the Conservative Party of Canada grapples with a breach exposing MPs' financial records.

In the realm of cybersecurity threats, a new wave of sophisticated attacks is on the rise. The Shai-Hulud worm is causing chaos in the npm ecosystem, and groundbreaking research reveals how AI can be manipulated to prioritize unethical actions, posing new challenges for AI safety. A critical zero-day attack marks a turning point in cybersecurity, exploiting vulnerabilities with unprecedented speed and precision.

Additionally, we spotlight critical vulnerabilities, including a flaw in Oracle Identity Manager under active exploitation, and new Fluent Bit vulnerabilities that threaten cloud security. Our CVE roundup highlights significant vulnerabilities, such as a heap buffer overflow in libpng and a buffer overflow in Fluent Bit's indocker input plugin, urging organizations to patch promptly to safeguard their systems.

Stay informed and vigilant as we navigate these complex cybersecurity challenges together. Your digital safety is our priority.

Top CVEs

1. CVE-2025-65018: A heap buffer overflow vulnerability exists in the libpng library from version 1.6.0 to before 1.6.51. This flaw occurs in the pngimagefinishread function when processing 16-bit interlaced PNGs with an 8-bit output format, allowing attacker-crafted PNG files to cause heap writes beyond allocated buffer bounds. The issue has been patched in version 1.6.51. Source: Vulners.
2. CVE-2025-12970: The extractname function in Fluent Bit's indocker input plugin is vulnerable due to copying container names into a fixed-size stack buffer without validating length. An attacker with control over container names can exploit this to cause a buffer overflow, leading to process crashes or arbitrary code execution. Source: Vulners.
3. CVE-2025-65998: Apache Syncope's AES encryption configuration for storing user passwords in the internal database uses a hard-coded default key. This allows attackers with database access to reconstruct original passwords. Users are advised to upgrade to versions 3.0.15 or 4.0.3 to resolve this issue. Source: Vulners.
4. CVE-2025-65500: A NULL pointer dereference vulnerability in the coapdtlsgeneratecookie function of OISM libcoap 4.3.5 can be exploited by remote attackers to cause a denial of service. This occurs via a crafted DTLS handshake that triggers SSLgetSSLCTX to return NULL. Source: Vulners.
