iOS and iPadOS: Insertion of Sensitive Information into Log File

Published Updated By the CyberSecBulletin desk

CVE-2026-28987 is a high-severity insertion of sensitive information into log file vulnerability in iOS and iPadOS from Apple, with a CVSS 3.1 base score of 7.5 out of 10. It can be exploited remotely over the network by an unauthenticated attacker, without any action from a user. The record lists versions 18.7.9, 26.5 as the first without the flaw, so updating iOS and iPadOS to one of those releases or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.44% chance of exploitation within 30 days, which is low compared with other CVEs.

High severity with no evidence of exploitation so far.

What to do

  1. Update iOS and iPadOS to 18.7.9 or 26.5, whichever matches your release line, or a later version.
  2. Update macOS to 14.8.7 or 15.7.7 or 26.5, whichever matches your release line, or a later version.
  3. Update tvOS to 26.5 or a later version.
  4. Read the advisory on support.apple.com for workarounds and exact fixed builds.
  5. Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.

The underlying weakness: Insertion of Sensitive Information into Log File

The product writes sensitive information to a log file.

How developers prevent this class of flaw

  • Consider seriously the sensitivity of the information written into log files. Do not write secrets into the log files.
  • Remove debug log files before deploying the application into production.
  • Protect log files against unauthorized read/write.
