  "details": "A vulnerability was identified in the Twig sandbox security policy that allowed database write operations when `cms.safe_mode` is enabled. Backend users with Developer permissions could use Twig template markup to execute insert, update, and delete operations on any database table through the query builder, which is included in the sandbox allow-list.\n\n### Impact\n- Arbitrary database writes including modification or deletion of any table\n- Requires authenticated backend access with Developer permissions\n- Only relevant when `cms.safe_mode` is enabled (otherwise direct PHP injection is already possible)\n\n### Patches\nThe vulnerability has been patched in v3.7.14 and v4.1.10. Write operations such as `insert`, `update`, `delete`, and `truncate` are now blocked on query builder and model objects within the Twig sandbox. All users are encouraged to upgrade to the latest patched version.\n\n### Workarounds\nIf upgrading immediately is not possible:\n- Restrict Developer tool access to fully trusted administrators only\n\n### Reporter\n- Reported by [Chris Alupului](https://github.com/neosprings)",

  "details": "### Description\n\n`symfony/html-sanitizer` lets applications sanitise untrusted HTML. `UrlAttributeSanitizer` is the visitor responsible for validating URL-valued attributes and stripping dangerous schemes from them; it runs on every element regardless of configuration. Whether an attribute is *kept* is decided by the element/attribute allow-list; validating the *scheme* of a URL attribute is solely `UrlAttributeSanitizer`\u0027s responsibility.\n\n`UrlAttributeSanitizer::getSupportedAttributes()` returned only `[\u0027src\u0027, \u0027href\u0027, \u0027lowsrc\u0027, \u0027background\u0027, \u0027ping\u0027]`. The HTML URL-valued attributes `action` (`\u003cform\u003e`), `formaction` (`\u003cbutton\u003e`, `\u003cinput type=image\u003e`), `poster` (`\u003cvideo\u003e`) and `cite` (`\u003cblockquote\u003e`, `\u003cq\u003e`, `\u003cdel\u003e`, `\u003cins\u003e`) were missing from that list, so `DomVisitor` never invoked scheme validation for them. As a result, when a configuration admits one of those attributes, a `javascript:` URI in it survived sanitisation.\n\n### Conditions for exploitation\n\n`allowSafeElements()` is **not** affected: `\u003cform\u003e` and the `formaction` attribute are both flagged unsafe in `W3CReference`, and `allowElement(\u0027form\u0027)` resets the element\u0027s attribute list. Reaching the vulnerable attributes requires a deliberately permissive configuration, for example:\n\n* `\u003cform\u003e` + `action`: `allowElement(\u0027form\u0027, \u0027*\u0027)`, `allowElement(\u0027form\u0027, [\u0027action\u0027, \u2026])`, `allowElement(\u0027form\u0027)-\u003eallowAttribute(\u0027action\u0027, \u0027form\u0027)`, or the `allowStaticElements()` preset (whose docblock already warns the output \"may still contain other dangerous behaviors\");\n* `\u003cbutton\u003e` / `\u003cinput type=image\u003e` + `formaction`: `allowElement(\u2026, \u0027*\u0027)`, `allowAttribute(\u0027formaction\u0027, \u2026)`, or `allowStaticElements()`;\n* `\u003cblockquote\u003e` / `\u003cq\u003e` / `\u003cdel\u003e` / `\u003cins\u003e` + `cite`, or `\u003cvideo\u003e` + `poster`: similarly via `\u0027*\u0027`, `allowAttribute()`, or `allowStaticElements()`.\n\nFor the `action` / `formaction` cases the victim must additionally submit the form or click the button.\n\n### Resolution\n\n`UrlAttributeSanitizer` now also handles `action`, `formaction`, `cite` and `poster`. `action` / `formaction` / `cite` are validated against the link schemes (like `\u003ca href\u003e`, so `javascript:` is rejected and `data:` is dropped too); `poster` is validated against the media schemes (so `data:` images keep working). The behaviour of `\u003ca href\u003e` and `\u003cimg src\u003e` is unchanged.\n\nOne behaviour change to be aware of: a relative `action=\"/submit\"` on an allowed `\u003cform\u003e` is now dropped by default (the same as `\u003ca href\u003e` / `\u003cimg src\u003e` today); `-\u003eallowRelativeLinks()` re-enables it.\n\nThe patch for this issue is available [here](https://github.com/symfony/symfony/commit/26a598fcfc4f903cc55ff202f642ee621839825e) for branch 6.4.\n\n### Credits\n\nSymfony would like to thank Himanshu Anand and R\u00e9mi Pelloux for reporting the issue and Nicolas Grekas for providing the fix.",

  "details": "`jackson-databind`\u0027s `PolymorphicTypeValidator` (PTV) is the primary safety mechanism guarding polymorphic deserialization. When polymorphic typing is enabled and a type identifier contains generic parameters (i.e. the type ID string contains `\u003c`), `DatabindContext._resolveAndValidateGeneric()` validates **only the raw container class name** (the substring before `\u003c`) against the configured PTV.\n\nIf the container type is approved, the method parses the full canonical type string via `TypeFactory.constructFromCanonical()` and returns the fully parameterized type **without ever validating the nested type arguments** against the PTV. The nested type arguments are then resolved, instantiated, and populated as beans during deserialization.\n\nAn attacker who controls the type ID can therefore place a denied class as a generic type parameter of an allowed container \u2014 for example `java.util.ArrayList\u003ccom.evil.Gadget\u003e` when only `java.util.ArrayList` is allow-listed. The container passes the PTV check; `com.evil.Gadget` is loaded via `Class.forName(name, true, loader)`, instantiated, and its properties are set from attacker-controlled JSON. This completely bypasses an explicitly configured PTV allow-list.\n\nThis is the same vulnerability class responsible for the historical sequence of jackson-databind deserialization CVEs; here it manifests as a validator bypass rather than a missing deny-list entry.\n\n\n## Impact\n\n- **Bypass of the PTV allow-list**, including the recommended `BasicPolymorphicTypeValidator` configured with name-prefix allow rules.\n- **Arbitrary class instantiation** of any type assignable to the container\u0027s element/parameter position, with attacker-controlled property values (setter/field injection).\n- **Potential unauthenticated remote code execution** when a class with exploitable side effects (JNDI lookup, JDBC/connection-pool gadgets,`TemplatesImpl`-style loaders, etc.) is present on the classpath.\n\nApplications that accept untrusted JSON and rely on a configured PTV \u2014 the documented, security-conscious configuration \u2014 are affected.\n\n\n## Proof of Concept\n\nConfiguration restricting polymorphic deserialization to a single safe container:\n\n```java\nBasicPolymorphicTypeValidator ptv = BasicPolymorphicTypeValidator.builder()\n        .allowIfSubType(\"java.util.ArrayList\")\n        .build();\n\nObjectMapper mapper = JsonMapper.builder()\n        .polymorphicTypeValidator(ptv)\n        .build();\n```\n\nMalicious payload (`Wrapper.value` is `Object` with `@JsonTypeInfo(use = Id.CLASS, include = As.WRAPPER_ARRAY)`):\n\n```json\n{\"value\":[\"java.util.ArrayList\u003ccom.evil.EvilGadget\u003e\",[{\"cmd\":\"calc.exe\"}]]}\n```\n\nOn vulnerable versions, `com.evil.EvilGadget` is instantiated and its `cmd` property is set, despite only `java.util.ArrayList` being allow-listed. On `2.18.8` / `2.21.4` / `3.1.4` the deserialization throws `InvalidTypeIdException` before instantiation.\n\n**Variant payloads** (all bypass an `ArrayList`/`HashMap` allow-list):\n\n| Type ID | Smuggled type position |\n|---|---|\n| `java.util.ArrayList\u003cEvil\u003e` | list element |\n| `java.util.HashMap\u003cEvil,String\u003e` | map key |\n| `java.util.HashMap\u003cString,Evil\u003e` | map value |\n| `java.util.ArrayList\u003cjava.util.ArrayList\u003cEvil\u003e\u003e` | nested element |\n| `java.util.ArrayList\u003cEvil[]\u003e` | array element |\n\n---\n\n## Patches\n\nFixed in **2.18.8**, **2.21.4** and **3.1.4** via the changes for [FasterXML/jackson-databind#5988](https://github.com/FasterXML/jackson-databind/issues/5988), commit `434d6c511`. The fix adds recursive validation of each non-trivial type parameter (and array element types appearing as parameters) through the full PTV chain, with documented exemptions for `Object` (wildcard resolution) and `Enum` types.\n\n`PolymorphicTypeValidator` was added in 2.10.0 so vulnerability N/A for versions prior to that.",

In affected versions, a command request using abbreviated encoded-command flags could use an alias form not recognized by the allowlist parser.\n\nThis advisory is scoped to the named feature and configuration.

Practical impact depends on the operator\u0027s configuration and whether lower-trust input can reach that path.\n\n### Patched Versions\n\nThe first stable patched version is `2026.5.12`.\n\n### Mitigations\n\nAvoid allowlisting PowerShell wrapper forms and require approval for encoded commands until patched. As general hardening, keep channel and tool allowlists narrow, avoid sharing one Gateway between mutually untrusted users, and disable the affected feature when it is not needed.",
