  Stack-Based Buffer Overflow in F5 BIG-IP APM Enables Unauthenticated RCE
  CVE-2025-53521 is a stack-based buffer overflow (CWE-121) in F5 BIG-IP's Access Policy Manager (APM) that allows remote code execution. The flaw is triggered when a virtual server is configured with an APM access policy and receives specific malicious network traffic; no authentication or user interaction is required per the CVSS 4.0 vector. An attacker who exploits it gains remote code execution on the BIG-IP device, and in observed intrusions attackers have deployed a fileless Linux rootkit (dubbed 'PoisonedRefresh') that injects a PHP web shell into server memory to evade disk-based scanning. Any F5 BIG-IP deployment with an APM access policy configured on a virtual server is potentially affected; versions that have reached End of Technical Support are not evaluated by the vendor. The vulnerability is being actively exploited in the wild — it was added to CISA's Known Exploited Vulnerabilities catalog on 2026-03-27, with active exploitation and in-memory malware campaigns confirmed in press reports, though ransomware use is unknown.

  Authentication Bypass and Account Takeover in N-able N-central (Incomplete Patch)
  CVE-2026-18577 is an authentication bypass (CWE-288) in N-able's N-central RMM platform caused by an incomplete patch for the earlier vulnerability CVE-2026-18556. Because the original fix can be bypassed via an alternate path or channel, a remote, unauthenticated attacker needs no privileges or user interaction, though the attack requires meeting exploit-specific conditions (high attack complexity, CVSS 4.0: 8.2 High). Successful exploitation lets the attacker bypass authentication and take over N-central accounts, gaining high-impact access to the management console with limited direct effects on downstream services. All N-central versions through 2026.3.1 are affected. Exploitation is confirmed in the wild: the flaw was added to CISA's KEV on 2026-08-03, EPSS estimates a 54.1% chance of exploitation within 30 days (99th percentile), and news reports say attackers kept exploiting it even as N-able shipped successive hotfixes; ransomware use is currently unknown.

  Authentication Bypass (Alternate Path/Channel) in N-able N-central
  N-able's N-central RMM platform contains an authentication bypass (CWE-288) in which an alternate path or channel allows requests to skip the normal authentication check. An unauthenticated attacker can trigger it by sending requests through that alternate path without valid credentials, gaining unauthorized access to the N-central management interface; because N-central is remote monitoring and management software run by managed service providers, such access can expose management functions across downstream customer environments. N-able N-central deployments are affected; the available data does not specify affected version ranges or fixed builds. The flaw was added to CISA's Known Exploited Vulnerabilities catalog on 2026-08-04, confirming exploitation in the wild, with a high EPSS of 40.2% (99th percentile), no CVSS score yet, no public PoC, and undetermined ransomware use; related reporting describes a recent string of N-central hotfixes, including fixes for unauthenticated remote code execution.
