Xcode Authorization Flaw Allows Access to Sensitive User Data

An authorization issue was addressed with improved state management. This issue is fixed in Xcode 27.2. An app may be able to access sensitive user data.

This issue was addressed with improved handling of symlinks. This issue is fixed in Xcode 27.2. An app may be able to read arbitrary files.

This issue was addressed by enforcing library validation on the affected binaries. This issue is fixed in Xcode 27. An app may be able to break out of its sandbox.

Out‑of‑Bounds Read During Xcode Binary Parsing Leading to Application Crash

An out-of-bounds read was addressed with improved input validation. This issue is fixed in Xcode 27. Parsing a maliciously crafted binary may lead to unexpected tool termination.

An input validation issue was addressed with improved input validation. This issue is fixed in Xcode 27. Parsing a maliciously crafted binary may lead to unexpected app termination.

Xcode Library Validation Bypass Enables Sandbox Escape

This issue was addressed by enforcing library validation on the affected binaries. This issue is fixed in Xcode 27. A malicious app may be able to break out of its sandbox.

libssh2: Integer overflow in transport read resulting in out of bounds write

An integer overflow flaw which could lead to an out of bounds write was discovered in libssh2 before 1.8.1 in the way packets are read from the server. A remote attacker who compromises a SSH server may be able to execute code on the client system when a user connects to the server.

jackson-databind: default typing mishandling leading to remote code execution

SubTypeValidator.java in FasterXML jackson-databind before 2.9.9.2 mishandles default typing when ehcache is used (because of net.sf.ehcache.transaction.manager.DefaultTransactionManagerLookup), leading to remote code execution.

Permissions issue enabling application to access user‑sensitive data

A permissions issue was addressed with improved validation. This issue is fixed in Xcode 27, macOS Golden Gate 27. An app may be able to access user-sensitive data.

Apache Log4j2 JNDI features do not protect against attacker controlled LDAP and other JNDI related endpoints

Apache Log4j2 2.0-beta9 through 2.15.0 (excluding security releases 2.12.2, 2.12.3, and 2.3.1) JNDI features used in configuration, log messages, and parameters do not protect against attacker controlled LDAP and other JNDI related endpoints. An attacker who can control log messages or log message parameters can execute arbitrary code loaded from LDAP servers when message lookup substitution is enabled. From log4j 2.15.0, this behavior has been disabled by default. From version 2.16.0 (along with 2.12.2, 2.12.3, and 2.3.1), this functionality has been completely removed. Note that this vulnerability is specific to log4j-core and does not affect log4net, log4cxx, or other Apache Logging Services projects.

Information Disclosure in Xcode via Malicious App

The issue was addressed with improved checks. This issue is fixed in Xcode 16.3. A malicious app may be able to access private information.

Arbitrary File Overwrite Vulnerability in Xcode via Improper State Management

This issue was addressed through improved state management. This issue is fixed in Xcode 16.3. An app may be able to overwrite arbitrary files.

Xcode Sandbox Bypass Grants Unauthorized File Access

The issue was addressed with improved checks. This issue is fixed in Xcode 26. An app may be able to read and write files outside of its sandbox.

Crash from Overly Large Path Values in Xcode

The issue was addressed with improved checks. This issue is fixed in Xcode 26. Processing an overly large path value may crash a process.

Potential Sandbox Escape in Apple Xcode via Improper Privilege Control

This issue was addressed with improved checks. This issue is fixed in Xcode 26. An app may be able to break out of its sandbox.

Xcode Permissions Issue Allowing Apps to Bypass Privacy Preferences

A permissions issue was addressed with additional restrictions. This issue is fixed in Xcode 16.3. An app may be able to bypass Privacy preferences.

Untrusted search path vulnerability in OpenBase SQL 10.0 and earlier, as used in Apple Xcode 2.2 2.2 and earlier and possibly other products, allows local users to execute arbitrary code via a modified PATH that references a malicious gzip program, which is executed by gnutar with certain TAR_OPTIONS environment variable settings, when gnutar is invoked by OpenBase.

The WOHyperlink implementation in WebObjects in Apple Xcode tools before 3.1 appends local session IDs to generated non-local URLs, which allows remote attackers to obtain potentially sensitive information by reading the requests for these URLs.

OpenBase SQL 10.0 and earlier, as used in Apple Xcode 2.2 2.2 and earlier and possibly other products, allows local users to create arbitrary files via a symlink attack on the simulation.sql file.

Buffer Overflow Causing Denial of Service in Xcode

A buffer overflow was addressed with improved bounds checking. This issue is fixed in Xcode 26.1. A user in a privileged network position may be able to cause a denial-of-service.
